The tension in the courtroom could only be outmatched by the gravity of the accusations as Thomas Stanko stood trial for the disappearance and alleged murder of his ex-girlfriend, Cassandra Gross. Stanko, adamant about his innocence, took the stand in a Westmoreland County courtroom, where he tried to pin the blame on another individual for Gross' fate, and set forth a challenge to take a lie detector test, reported TribLIVE.

According to testimony covered by WTAE, the 55-year-old Stanko described April 7, 2018, the day Gross was last seen, as uneventful with both of them burning unwanted items in a barrel. Gross' glasses were found in that same barrel, with Stanko stating they fell accidentally during the burning. This detail closely follows his assertion that he saw Gross leave to go shopping and never encountered her again. During the cross-examination, Stanko refuted insinuations of stalking and attempted break-ins at Gross' home and remained resolute, saying, "I did not," when asked if he killed her.

Jury deliberations began amidst summations that painted Stanko as either a wrongly accused man or a jealous ex-partner capable of murder. The prosecutors brought forth 32 witnesses and over 360 court exhibits, including emotional testimony from Stanko's ex-wife Cathy Vokes. She detailed accounts of domestic violence and threats reminiscent of behaviors Gross allegedly experienced, TribLIVE reported.

Assistant District Attorney Jim Lazar meticulously probed into Stanko's narrative during the trial. When confronted with letters, voicemails, and internet searches that suggested a darker side to Stanko's relationship with Gross, Stanko retorted, "I wrongfully accused her of cheating, but that does not make me a murderer," as detailed by WTAE. In a twist, Vokes gave a harrowing account of her own experiences with Stanko, her voice breaking as she recalled physical and verbal abuse, plus threats that echoed the chilling "he told me he would kill me and no one would ever find me," as divulged by TribLIVE.

Now, as the trial edges closer to its conclusion, Stanko could face mandatory life without parole if found guilty of first-degree murder. With the evidence and testimonies laid bare, the jury's verdict will determine Stanko's fate.
