DNA clears Missouri man Mike Wilkerson in 1997 sex assault of teen

KANSAS CITY, Mo. -- A Missouri man who spent nearly two decades in mental hospitals after entering a disputed plea in the 1997 sexual assault of a teenager has been cleared of the crime after genetic evidence was re-tested and excluded him as a suspect.

The top prosecutor in southwestern Missouri's Jasper County dropped the case against 58-year-old Mike Wilkerson last Friday, citing the recent DNA testing conducted on a cigarette butt and a condom found at the scene.

The victim, who was 17 at the time, said she was sexually assaulted by a gunman who entered her home after pretending to be lost, and she identified Wilkerson as her attacker from a photo lineup.

Wilkerson pleaded not guilty by reason of insanity in 2000, and by Missouri law, he was ordered committed indefinitely to mental hospitals. In such cases, defendants remain in the state Department of Mental Health's custody until they prove they no longer have a mental illness that could endanger themselves or others. Because Wilkerson's case involved a violent sex act, he faced the added burden of showing he understood the criminality of it - essentially admitting it. But Wilkerson has been unwavering in professing his innocence, his appeals attorney, Bill Fleischaker, said Wednesday.

"He stuck to his guns, and you've got to admire his courage," Fleischaker told The Associated Press. "There was an easy out, and he wasn't willing to take it."

A judge last year threw out Wilkerson's plea, leading to Wilkerson being freed on bond in January pending a new trial and to prosecutors taking a fresh look at the evidence.

"I lost 20 years," Wilkerson told The Joplin Globe, lamenting that he missed such things as weddings of two children. But "I'm ready to celebrate."

Calls by The Associated Press to Wilkerson's cellphone Wednesday went unanswered.

Jasper County Prosecutor Theresa Kenney said prosecutors who initially handled the case failed to consider all of the evidence. At that time, only the condom found at the scene was tested for DNA, but that examination proved inconclusive with the technology available then.

Fleischaker said at the time Wilkerson pleaded not guilty by reason of insanity at his trial attorney's urging, he was financially troubled, bipolar and "very mentally ill."

"Mike didn't understand when he entered the not guilty by reason of mental disease or defect - and the fact he had no other defense - that that's the legal equivalent of saying you did it," Fleischaker said. "It's the legal equivalent of saying, 'I'm guilty but insane,' and that's the way it was treated.

"There were a lot of things done wrong that led to Mike being in the situation he was in."

Fleischaker said a DNA test he ordered on the cigarette butt in 2011 excluded Wilkerson as the source of the genetic material on it. He said Wilkerson's legal team didn't have access at the time to swabs of DNA taken from the condom.

Last year, a judge threw out Wilkerson's plea because state psychiatrists never concluded he was insane at the time of the crime. Wilkerson later pleaded not guilty, prompting prosecutors to resubmit the evidence for DNA testing, which ultimately cleared him.

"It's been a long road," Fleischaker said. "The key to this thing is we felt all along the DNA would exonerate him. The problem is there were a lot of procedural hurdles we had to get over."
