Thus began a lengthy search that will go on for years without answers. The authorities believed her boyfriend at first – with whom she supposedly argued a lot – but he had a strong argument.

Authorities continued to look into her workplace because it was close to where her body was discovered.

Mark Libecki, Teresa’s co-worker, confirmed that she was restless on that particular day. Isaac Alvarez, with whom Teresa was in a contentious argument that day, was chosen by the others.

Soon the threads of the authorities ran out, and the case went unresolved. Authorities eventually discovered a match from the initial list of suspects after some recent DNA testing developments, and the DNA matched that of the most likely suspect.

It was the property of Mark Libicki. Further investigation indicated that Libicki’s shoes matched the footprints discovered at the site. Then the police tracked down his old car, which showed signs of Teresa Wisowski’s blood.

Authorities detained Libeki after collecting all necessary evidence. He allegedly reviewed his story several times, accusing a co-worker named Tom Thompson of her murder and threatening Libecki with violence if she did not speak up.

Libecki insisted he was innocent. The authorities allegedly believe that Libecki made a move on Teresa that evening because he had romantic interests in her. He violently stabbed her to death after she refused him. He was sentenced to life imprisonment with no chance of release.
