A possible Miranda violation, a missing taped âconfession,â and an improperly charged girlfriend among the flaws in Vince Biskupicâs case

By Phoebe Petrovic and Dee J. Hall, Wisconsin Watch and WPR
This is the fifth installment of Open and Shut, a seven-part podcast and online series investigating the virtually unchecked power of prosecutors. See the entire project at wpr.org
In the summer of 2000, 19-year-old Shanna Van Dyn Hoven had just finished her first year at the University of Wisconsin-Madison.
She was back home in Kaukauna, Wisconsin. And one Sunday afternoon, she went for a jog on a route she often followed. Van Dyn Hoven reached the last leg, a stretch of hill between woods and a quarry.
Thatâs when a neighbor, David Carnot, the son of a recently retired police officer, heard her screaming. He stopped his yard work and ran through the copse of trees between his house and the road. He later told his story to local news reporters.
âYou could hear the fear in her voice, that she feared dying,â Carnot said. âYou could tell that something was drastically bad. ⊠I started hollering, âSomebody dial 9-1-1.â But nobody was here â nobody heard me.â
Carnot says he found Van Dyn Hoven lying on the ground, bleeding. Above her stood a man who seemed to have gotten out of a pickup truck.
âThe minute I said something, he just looks at me, and then (got) into the truck and drive right for me.â
Carnot says he ran towards a fence at the quarryâs entrance. As he started to climb over it, the truck rammed the fence and struck him in the leg. The driver then fled the scene. A fishing boat on a trailer bounced behind the truck.
Soon after, police were flying down the road in another part of Kaukauna in hot pursuit of that Chevy pickup. Police had seen it driving erratically through the city on three tires. When the truck finally went into the ditch, officers approached it, guns drawn.
The driver, shirtless, was wearing jean shorts and sandals. Police said he appeared to have dried blood on his arms, chest, stomach, legs and feet.
On his upper arm, he had a tattoo that read âKEN.â Police identified him as Ken Hudson.
Investigators say they found a bloody knife on the driverâs side floor and Van Dyn Hovenâs blood on the passenger seat. And the case against Ken Hudson seemed open and shut.
But a Wisconsin Watch and WPR investigation found a litany of holes in this apparently rock-solid case that suggest the prosecution by Outagamie County District Attorney Vince Biskupic was anything but open and shut.
Certified letters asking detailed questions about the Hudson case, emails and phone calls to Biskupic and his attorney were not returned.
Girlfriend targeted
One curious aspect of the case involves Biskupicâs prosecution of Hudsonâs then-girlfriend Danita Scharenbroch, who has since married and uses the last name of Metko.
At the time of the murder, Metko and Hudson had been dating for about a year. They lived together with her two boys at a mobile home park in a village near Kaukauna. The morning of the murder, theyâd all been up north together, camping and fishing.
Metko received the news of Hudsonâs arrest with disbelief, shock.
âI didnât think Ken was capable of that. I mean, he was a bumbling, stumbling fool half the time,â Metko says. âI always said he was an accident waiting to happen, but not a murderer.â
But as Kaukaunaâs assistant police chief would later tell her â everybodyâs capable of murder.
Says Metko: âIâm believing everything theyâre telling me. He did it, they found the knife ⊠I mean, I have no reason ever not to believe the police!â
But as the investigation continued, Metko had a number of unsettling experiences. She says the police told her that she might be a suspect â even though at the time of the murder, she was at home waiting for a pizza delivery.
And early on, officers asked Metko to drive back north to figure out where Hudson had bought the knife â which seemed odd because police had already found the receipt for the knife from a nearby Kmart in Hudsonâs pocket.
Metko eventually felt so rattled that she hired a lawyer for herself. And her faith in the police faded.
âI started to believe maybe Ken really wasnât guilty of this,â she recalls. âMaybe it wasnât like they were saying.â
Metko receives a divine message
Metko prayed for guidance. The answer, she says, came to her while she was doing the laundry.
âAnd all of a sudden it was like, I could hear this voice. I know. It sounds funny. You got to have faith to believe it. It was just like, it was like âStick by him and help him.â â
Metko walked to the mailbox and found a letter from Hudson. It said: âNobodyâs ever stuck by me and helped meâ â the same message she believed she got from God.
And so she did. Metko started visiting Hudson in the Outagamie County Jail.
After several months, Kaukauna Assistant Police Chief John Manion and another officer visited Metko at the Subway sandwich shop she managed. They told her not to visit Hudson anymore. There was a no-contact order involving any potential witnesses, they said.
Metko called her attorney.
âHe goes, âDanita, just stay away from anything to do with Biskupic. He will pull you into this. You have nothing to do with it. He doesnât care about you or your kids,â â Metko recalls. âSo I listened to him.â
So for a while, she stopped visiting Hudson. But eventually, she consulted Hudsonâs attorney, who told her it was okay to visit Hudson, and she resumed her trips.
And then, in February 2001, police paid her another visit.
This time, they asked Metko to come in for a talk. She says she was âstupidâ for not calling her lawyer.
When Metko and the officers arrived at the Outagamie County Justice Center, officers arrested Metko. Her supposed crime: talking to Hudson on the phone and allegedly violating that no-contact order the police had warned her about. As a condition of release, Metko had to agree not to talk to Hudson or âIâd be thrown into jail until my court date in May.â
And so, about two weeks before Hudsonâs trial, Metko suddenly stopped accepting his calls. And that, Hudson says, had a real impact on his case.
Hudsonâs version of events
For 21 years, Hudson has worked tirelessly in his prison cell, poring over police reports and photographs, scrutinizing their contents for any contradictions.
In Hudsonâs telling, he was in the wrong place at the wrong time.
âI see the victim standing on the side of the road waving her arms and screaming,â Hudson recounts. âSo I seen that she was covered in blood. And so I get out of my truck and I run around to where she was standing. And I’m like, âWhat happened? Whatâs going on? Whatâs going on?â And she couldnât say nothing at that point. ⊠So Iâd open up the passenger side door and I told her to sit on the seat, which she did. Right at that time, I hear screaming in the woods, a male screaming.â
That was Carnot, the neighbor who told of running to Van Dyn Hovenâs aid. Hudson says at that point, Van Dyn Hoven fled the truck and crumpled to the ground.
Hudson says he thought Carnot was the killer â and he was scared. So he jumped into his truck and hit the accelerator. He smashed into the fence, then reversed, and took off.
A couple blocks away, Hudson noticed the fishing boat he was towing falling off the trailer. So he stopped, released it and left it lying on the side of the road. Soon, a patrol officer spotted the odd vehicle with a missing tire and empty boat trailer.
âAnd then he started chasing me and I panicked because I had marijuana on me and I was drinking and my driverâs license was revoked,â Hudson says.
Hudson had also taken some Valium. As for what police found when they pulled Hudson over â the knife in the truck and the blood on his body â they became the focus of multiple motions and appeals.
String of lawyers â and then none
A U.S. Supreme Court decision guarantees everyone facing felony criminal charges an attorney, even if they canât pay. Hudson had a number of court-appointed lawyers. His first set withdrew because of a conflict.
Before doing so, however, they entered an insanity plea on Hudsonâs behalf â which claimed he did not have the capacity to understand his actions.
But other attorneys left or were fired by Hudson. They wanted him to strike a plea deal; he wanted to prove his innocence.
As the trial approached, Outagamie County Circuit Judge Harold Froehlich agreed to appoint one last lawyer, telling Hudson, âYou better learn to cooperate with your new attorney because there wonât be another one.â
But Hudson sought to fire him too. Froehlich gave Hudson 11 days to hire his own lawyer. And thatâs why Danita Metkoâs arrest became so important.
The weekend after Froehlich issued this deadline, Hudson called Metko numerous times as they worked to line up money from his uncle in New York for a private attorney.
That Monday morning â with seven days left until Hudson needed to hire a new lawyer â Metko headed to her shift at Subway.
âAnd my sister, she called me at work in the morning and said âLook it, Ken called me. He couldnât call you; the number was blocked from the jail. He couldnât call our Mom; the number was blocked. He couldnât call anyone in New York; the number was blocked.â â
Thatâs the same day that officers arrested Metko â and she says a judge banned her from contacting Hudson. She could no longer help him get a lawyer.
So, just two weeks before trial was set to begin, Hudson returned to court without a new attorney. Froehlich said Hudson needed to represent himself. Representing oneself in court is a constitutional right. But itâs one that a legal scholar once called âthe right to shoot oneself in the foot.â
Hudsonâs trial a âcircusâ
Hudsonâs trial took place in March 2001, about eight months after Van Dyn Hovenâs murder. Hudson wasnât totally alone at the defense table. Froehlich had ordered Ed Carns â the last attorney Hudson had fired â to remain as standby counsel, basically coaching Hudson through court procedure.
Biskupic opened the stateâs case, telling jurors, âThe defendantâs actions relate to his anger, to rage and ultimately evil.â
Biskupic argued Hudson was mad at Metko and his mother â whom heâd fought with the weekend that Van Dyn Hoven died.
âYouâll learn from the evidence and testimony that peace met anger,â the district attorney said, âthat innocence met evil, that flesh was met with a blade, and ultimately life met death.â
At the start of the trial, Hudson asked the judge to suppress a key piece of testimony. On the night of the murder, the police took Hudson to the hospital to be checked for injuries. While he was there, he was swabbed for evidence and read his Miranda rights. Hudson says he asked for a lawyer.
But police never called one. And hours later, police say, Hudson confessed on videotape to killing Shanna Van Dyn Hoven.
When Hudsonâs trial began, he sought to keep that confession from being entered into evidence. Biskupic told the judge that Hudson had not made an âunambiguous requestâ for a lawyer and therefore had not invoked his right to counsel.
Courts have ruled that police only have to give you a lawyer if you clearly, specifically ask for one. The judge believed Biskupic and ruled that testimony about the confession was in.
However, police had recorded audio of Hudson at the hospital. It captured Hudson being read his Miranda rights: The right to remain silent, the right to consult with an attorney. As prosecutor, Biskupic would have had access to that tape.
The state says it gave the tape to Hudsonâs investigator. But for reasons that are still not clear â partly because the investigator has since died â Hudson never received the tape.
And, speaking of tapes, there was another problem with that alleged confession from the night of the murder. The videotape of that confession does not exist.
At trial, the police testified the videotape had accidentally erased itself. Hudson brought this up, but it just became part of the bizarre spectacle of a man representing himself at his own murder trial â what retired Green Bay TV reporter Jerry Burke described as âa circus.â
Biskupic: âYou told Officer Shephardson and Manion you forced the girl in the truck.â
Hudson: âI never told them that. Whereâs the audio and video? That they did the recording, but itâs, itâs erased. Where is that video, Vince Biskupic?â
For those keeping score, thatâs two tapes â the video tape of Hudsonâs alleged confession that had somehow erased itself, and the audio tape that Hudson says he never received â the one where he said he clearly asked for a lawyer.
Hudsonâs claim: I was framed
On the third day of trial, Hudson submitted a motion to withdraw his insanity plea, insisting he hadnât committed the crime at all.
And Hudson didnât just argue that he was innocent. He claimed he was framed.
Hudson testified that police tore open the package of a hunting knife heâd bought earlier that afternoon, smeared it with blood and planted it on the driverâs side floor of his truck. He showed the jury photos of the inside of his truck, saying the knife appeared to move between frames.
As for the blood on Hudsonâs legs? He said Kaukauna police officer Robert Patschke poured it on him.
âWhen I was in the back of the squad car, the officer threw that blood on me,â Hudson testified. âI said, âWhat are you doing? Stop doing that. What are youse doing to me?â â
Biskupic outlined Hudsonâs incredible claims in a question: âAnd youâre saying the police walked up to your car with a bucket of blood, a bloody knife and some other â probably her hand with her fingerprint and put it on your car, is that what youâre saying?â
In an interview, Hudson insists he is innocent.
âI just get really passionate because listen, this is the Godâs honest truth, that they did plant that knife in my truck and Patschke poured that blood on me,â Hudson says. âIâll take a lie detector right now and pass that with flying colors. Iâm telling the truth!â
Hudson didnât call any witnesses other than himself. Toward the end of trial, he threatened Carns and asked to be taken out of the courtroom. Thatâs when Carns delivered his closing argument â which completely undercut Hudsonâs case.
Carns argued essentially that the state hadnât proved that Hudson intended to kill Van Dyn Hoven. He said nothing about Hudsonâs claim that he was framed.
âThe evidence was so overwhelming,â recalls Burke, the former WBAY TV reporter who covered the trial. âWhen the evidence is the way it is, you go, âThis is a slam dunk.â And it pretty much was. I donât even remember how long the jury was out. It wasnât that long.â
Wisconsin does not have the death penalty. Hudson was given the maximum sentence â life in prison with no chance for parole.
Case against Metko tossed â twice
Burke wonders how things would have been different â perhaps less chaotic â if Hudson had âlet the attorney do his or her job.â What Burke didnât realize is Hudson was trying to hire a private attorney. Danita Metko was helping him. But when Metko was arrested and charged, those efforts ended.
And it turns out, Metkoâs arrest should never have happened. Biskupic assigned his deputy to handle the charges against Metko.
âFast forward to my court date in May, after â long after Ken got already convicted, and they threw it out,â Metko says. âThe judge said, âShe didnât commit a crime. There was no crime committed.â â
The circuit court and the state Court of Appeals both found that Metko didnât break any law. There wasnât even a law for her to break. That no-contact order was enforceable only against Hudson â not her.
So why was she arrested? Metko has a theory: âI was really the only person to help Ken. I was really his only liaison to maybe, possibly, getting him some money to help with an attorney.â
Evidence raises more questions
Even today, Metko is convinced of Hudsonâs innocence. She still visits him in prison, and sheâs put up a lot of her own money to help him with his appeals and DNA testing.
Among the many anomalies in the case is that Shanna Van Dyn Hovenâs blood wasnât where one might expect it to be.
Investigators found Van Dyn Hovenâs DNA on Hudsonâs right hand, but Hudson didnât leave any traces of blood on the surfaces he probably touched over the course of the 16-mile car chase. Investigators did not find it on the steering wheel, the gear shifter, the driverâs side floor where the knife was found â and not on the boat or the trailer.
And some of the places that looked like blood on Hudsonâs body were tested â and they had no DNA in them at all. DNA experts interviewed by Wisconsin Watch and WPR could not fully explain what caused the confusing DNA results.
But one thing is clear: There were definitely problems in Biskupicâs prosecution.
Remember the two tape recordings â one that supposedly erased itself and one that didnât make it Hudson? Several years after the trial, Hudson uncovered important new information about that evidence.
A forensic tape examiner looked into the Kaukauna Police Departmentâs video equipment. He concluded it was physically impossible for the videotaped confession to just accidentally âerase itself.â
And in 2007, Hudson finally received a copy of that other tape â the audio tape from the hospital that Hudson claimed had recorded him asking for a lawyer.
Says Hudson: âAnd those tapes prove beyond any doubt whatsoever that I was telling the God’s honest truth that I wanted to talk to a lawyer ⊠And that is something serious â for a defendant to be able to prove that these police were lying.â
The audio tape and transcript back up Hudsonâs claims. In the tape, he said, âI want to talk to a lawyer.â An unambiguous request.
In 2011, the Wisconsin Court of Appeals found the tape proved Hudson had clearly asked for an attorney. Hudson argued that by continuing to question him, the police had committed a so-called Miranda violation.
Normally, the remedy for a Miranda violation is to exclude any incriminating statements made after the defendant asked for a lawyer. In this case, it would mean that Hudsonâs alleged confession would be thrown out. He might even get a new trial.
âHarmless errorâ
But, the judges decided they didnât need to rectify the Miranda violation because of a legal principle called âharmless error.â
Bennett Gershman, a law professor at Pace University, explains how harmless error works: âIf the prosecutor did something wrong and then engaged in an error, what an appellate court will typically do, because they donât want to have to try cases over or over again, (is determine) how much did this violation matter?â
Harmless error acknowledges that an attorney made a mistake or broke a rule. But it doesnât fix the error, or sanction the person who made it.
Courts find harmless error when they determine âthat the other evidence was strong enough so that this evidence didn’t really matter. ⊠(and) the jury would have convicted anyway,â Gershman says.
Harmless error is a pretty common finding. The Innocence Network studied 660 confirmed cases of prosecutorial misconduct that occurred from 2004 to 2008. And in about 80% of the cases, the misconduct was considered âharmless.â
And of cases in that study where the courts determined the misconduct affected the verdict? Only one prosecutor was disciplined.
âAnd a rational prosecutor would probably say âIâve got the evidence. Itâs very, very strong. Iâm going to convict,â â Gershman says. âAnd ⊠â If I make errors, theyâre not going to be seen as that consequential.â So the rational prosecutor might have an incentive to engage in rule violations.â
But what if some day the courts decide that all of this â the Miranda violation, the lack of blood on the steering wheel, the questionable DNA evidence, even the arrest of Danita Metko â that all of this amounts to error that is considered âharmful?â
Kate OâBrien, a minor witness in the Hudson trial, has some thoughts on that. She told the jury she saw Hudson driving erratically on the day of the murder. OâBrien remembers sitting on the witness stand as she testified against Hudson feeling chills, like she was in the presence of evil.
And nearly 20 years later, OâBrienâs confidence in Hudsonâs guilt hasnât wavered.
âThere is no question in my mind that, yeah, the police may have screwed up, but this guy did it,â OâBrien says. âBecause those two possibilities can happen at the same time. They can mess it up with him still being really guilty.â
She is âscared to deathâ that Hudson could be released because of errors by Biskupic.
âThis guy was trusted by us,â she says of Biskupic. âI probably voted for the guy, and he just put so many people in jeopardy. And I’m furious.â
OâBrien adds: âAll the people who ⊠were witnesses in his cases are now potentially in danger, and thatâs unforgivable. Especially because this was just so open and shut. It should have been open and shut. â
