A jury on Thursday found a Troy Hill man guilty of first-degree murder in the 2018 shooting death of his girlfriend.

Calvin Stewart Alston, 59, will be sentenced to a mandatory life prison term by Allegheny County Common Pleas Judge Beth A. Lazzara on Oct. 20.

Alston was charged in the July 28, 2018, death of Vera Williams Butler, 54, who was killed in front of her home in the 200 block of Luray Street in Perry South.

A witness told investigators that they saw Alston and Butler arguing in the front seat of his pickup truck the evening of the shooting, and moments later heard three to four gunshots. The witness said when they looked out the window, they saw Alston shouting, “‘I told you so… I told you so,’” police said.

Butler died at the scene.

Another witness told police Alston immediately drove off. Investigators found Alston’s truck, but it wasn’t until Aug. 2 that he turned himself in, telling witnesses, “‘I need to turn myself in for murder. I murdered my girlfriend,’” the criminal complaint said.
