The next episode, titled 1999: Roadside Murder, will premiere on August 12, 2022. The investigation will transport viewers back to 1999, when the diligent Wesolowski was murdered by a co-worker.
Authorities spent years trying to solve the case, as the murder was anything but simple, and the perpetrator ended up the most unlikely suspect. Germantown, Wisconsin, a small town, was rocked by this tragedy and forever negatively affected.
What happened to Teresa Wesolowski? Who was she?
Theresa Wesolowski was born in Germantown, Wisconsin, in May 1977. She started working two jobs after receiving her degree in 1995 and began saving money for a house and a car. Theresa was praised by her friends and acquaintances for having a likeable personality and having great potential at work.
On the sad night of May 28, 1999, his promising life was abruptly cut short. She was discovered by one of her co-workers about a block from the plant where she worked. Supposedly, a co-worker found her face down on the floor with blood all around her. She had been stabbed numerous times, nearly 47 times, in the front of her body and in her neck, according to authorities.
Authorities immediately determined that the incident included a rabies murder. They ruled out robbery as a possibility after discovering that she had all of her money in her purse. The presence of tire and shoe prints in the area suggested the presence of another individual. There were allegedly no signs of a struggle on Theresa Wesolowski’s body, leading authorities to believe the killer caught her off guard.
Thus began a long search that would continue for years without answers. Authorities first believed his boyfriend, with whom he allegedly argued frequently, but he had a solid alibi.
Authorities continued to investigate his workplace because it was close to where his body was discovered.
Theresa’s co-worker, Mark Libecki, claimed that she was agitated on that particular day. Isaac Alvarez, with whom Theresa had a contentious argument that day, was singled out by others.
Also, Isaac was said to always have a knife on him. But allegedly Isaac also had an alibi and was able to pass the polygraph. Jerry Kirkpatrick was also under suspicion by the authorities, but he had a strong alibi.
Authorities soon ran out of leads and the case began to go unsolved. Authorities finally discovered a match from their initial list of suspects after some recent breakthroughs in DNA testing, and the DNA matched the most unlikely suspect.
It was owned by Mark Libecki. Further investigation indicated that Libecki’s shoes matched footprints discovered at the site. Police then tracked down his old car, which showed signs of Theresa Wesolowski’s blood.
The authorities detained Libecki after gathering all the necessary evidence. She allegedly reviewed her story several times, accusing a co-worker named Tom Thompson of killing her and threatening Libecki with violence if she didn’t talk about it.
Libecki insisted that he was innocent. Authorities allegedly believe that Libecki approached Theresa that night because he had romantic interests for her. He violently stabbed her to death after she rejected him. He received life in prison without the possibility of release.
The case will be further examined in the next episode of People Magazine Presents: Crimes of the ’90s, which will air on August 12, 2022.
