Trial begins for man accused of Christmas Day killing

A Bexar County jury who will decide the fate of a man accused of a Christmas Day 2015 slaying watched a video Tuesday that showed the victim being shot in the back of the head.

The murder trial of William Boyd Porter began Tuesday morning. Porter was 43 when he was arrested and charged in the death of Trayvouns Tramone Edwards on Dec. 25, 2015, near the gas pumps in a convenience store parking lot in the 2030 block of Goliad Road on the Southeast Side.

Porter’s attorney, Edward Branevec, told the jury his client shot Edwards to “protect” his daughter, who he believed had been kidnapped by the man.

Before prosecutors Gretchen Flader and Colby Austin Stout showed the jury surveillance video from the gas station, Porter motioned to his relatives in court to leave.

The store’s cameras caught the entire altercation at the gas station.

In the video, the panel saw Porter approach Edwards, 28, who appeared to have Porter’s daughter. Edwards swung at Porter and the teen ran to another vehicle. After some scuffling, Edwards is shot in the back of the head.

Homicide Detective Timm Angell testified that, from the video, it didn’t seem Edwards was a threat.

“It looked like he was executed,” Angell told the jury.

Shortly after the shooting, authorities released the surveillance video, which later helped police identify Porter, who was arrested a few weeks after the incident.

The state rested its case Tuesday afternoon and the defense is expected to begin calling witnesses this morning in 186th state District Court, presided by Judge Jefferson Moore.

There were 106 homicides in San Antonio in 2015, with Edwards’ death being the last of the year, according to a San Antonio Express-News special report that chronicles homicides in the city.

Murder is a first-degree felony. If convicted, Porter, now 45, faces a maximum term of life in prison.
