Closing arguments are underway Monday in the Murder trial of a man accused of killing a teen when she walked in during a home burglary in suburban Indian Head Park.
Prosecutors say John Wilson, Jr. stabbed 14-year old Kelli O'Laughlin with a kitchen knife when she walked in on him while he was robbing her family's home in 2011.
Police say he then stole the girl's cell phone and taunted her mother with text messages.
DNA evidence from a knit cap found in the home was later linked to Wilson.
Defense attorneys say the girl may have committed suicide.
Juror are expected to begin deliberations later this week.
