Twenty-year-old Treonna Washington was found dead in an alleyway in Aliquippa, Pennsylvania, the morning after a late Friday in August. A man walking his dog discovered her body near a set of stairs on Reed Street; an autopsy determined she had been shot in the head. The Pennsylvania State Police took over the case from the Aliquippa Police Department and treated it as a homicide.

Investigators focused on 25-year-old Jason Banks Jr., identified as Washington’s boyfriend. Evidence gathered for the prosecution included surveillance footage of Banks and Washington entering her Linmar Terrace apartment the evening of August 16, 2024, witness reports that the two had been arguing and that Washington had visible injuries afterward, and testimony from Banks’s roommate, Shakeirs Foster, who said he, Banks, and Washington were in the alley when he heard a gunshot and that Banks was the shooter. Foster also said Banks urged him to keep quiet.

Banks was arrested and charged with criminal homicide and simple assault. At trial, he testified in his own defense, claiming Foster was the shooter and that he fled because he feared Foster and Washington’s family. The jury convicted Banks of Washington’s murder and two counts of assault. He was sentenced to life in prison without parole. The murder weapon was not recovered.

Does anyone have information about Washington’s last movements in Aliquippa or the events at the Linmar Terrace apartment?
