What happened to Theresa Wesolowski? Who was she?
Theresa Wesolowski was born in Germantown, Wisconsin, in May 1977. She began working two jobs after receiving her degree in 1995 and began saving money for a home and a vehicle. Theresa was praised by her friends and acquaintances for having a likeable personality and for having great potential at work.
On the sad night of May 28, 1999, her promising life was cut abruptly. She was discovered by one of her coworkers almost a block from the plant where she worked. She was allegedly found face down on the ground with blood all around her by a coworker. She had been stabbed numerous times—nearly 47 times—on the front of her body and in her neck, according to authorities.
The authorities determined right away that the incident included a rage killing. They disregarded 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 supposedly no signs of a struggle on Theresa Wesolowski’s body, leading authorities to think that the murderer caught her off guard.

Thus began a protracted search that would go on for years with no answers. Authorities first believed her boyfriend—who she supposedly argued with frequently—but he had a solid alibi.
Authorities kept looking into her workplace because it was close to where her body was discovered.
Theresa’s coworker Mark Libecki asserted that she was agitated on that particular day. Isaac Alvarez, with whom Theresa had a contentious argument that day, was singled out by others.
Additionally, it was said that Isaac always had a knife on him. But Isaac also supposedly 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 started to become unsolved. Authorities ultimately discovered a match from their initial list of suspects after some recent advancements in DNA testing, and the DNA matched the most unlikely suspect.
It was Mark Libecki’s property. Further investigation indicated that Libecki’s shoes matched the footprints discovered at the site. Police then tracked down his old automobile, which turned up signs of Theresa Wesolowski’s blood.
Authorities detained Libecki after gathering all the necessary evidence. He allegedly revised his tale multiple times, accusing a coworker named Tom Thompson of killing her and threatening Libecki with violence if she didn’t speak out.
Libecki insisted that he was innocent. Authorities allegedly think Libecki made a move on Theresa that evening because he had romantic interests for her. He violently stabbed her to death after she turned him down. He received a life sentence without the chance of release.
