Theresa Wesolowski Cause of Death | 22-year-old Theresa Wesolowski was murdered by her co-worker, Mark Libecki. She died On May 28, 1999.
She was found lifeless next to her car, sge was reportedly stabbed more than 40 times. She parked about a half-block from Stone Container — a box factory where she worked — in Germantown, Wisconsin.
Libecki denied killing Wesolowski. He testified that on the night of the murder, around 11 pm, another co-worker named Tommy J. Thompson, who died of an overdose in 2003, met up with him at a location near his job to buy cocaine.
A short while later, Wesolowski arrived and joined Thompson in the backseat of his vehicle and began discussing something, but Libecki said he wasn’t sure what they were saying, and he said he didn’t want to know.
Libecki went on to say that after Thompson snorted the cocaine, he zoned out and before he knew it, Thompson was attacking Wesolowski in the backseat.
That’s when Libecki said he got out of the vehicle and opened the back door in an effort to get them out of his car, but it was at that time he saw blood and Wesolowski was slumped over.
He said he dragged her out of the car and put her body on the street, next to her vehicle. Before fleeing the scene, Libecki claimed that Thompson told him if he ever told anyone about what happened, he would kill him.
However, investigators weren’t buying his story as DNA evidence linked him to the murder. Libecki was arrested and charged with first-degree intentional homicide as a party to the crime.
He was found guilty of murdering Wesolowski and was sentenced to life in prison without the possibility of parole.
