A man accused of killing a 14-year-old Indian Head Park teen last month plans to plead not guilty, according to his lawyer.
John Wilson, 38, is accused of stabbing Kelli O'Laughlin in her home on Oct. 27. Police believe she victim had walked in on a burglary in progress.
Wilson appeared in court Monday for a brief hearing, the Chicago Tribune reports.
The suspect has long battled mental illness, but his lawyer, John P. Carroll, told reporters that Wilson will plead not guilty to first-degree murder and residential burglary charges at his court hearing later this week.
Wilson has been behind bars for 17 of the last 20 years and has been convicted on charges ranging from carjacking, spitting on a prison corrections officer, possessing a stolen vehicle, robbery and drug possession.
He was on parole at the time he's accused of committing this latest crime.
