A Thomaston man will spend the rest of his life behind bars after he was found guilty of murder in a fatal shooting at a Cobb County gas station in May of 2017.

Joseph Priester, 37, was sentenced to life in prison on Friday in the shooting death of 39 year-old Genaro Rojas-Martinez at a Texaco station on South Cobb Drive on May 15, 2017.

Rojas-Martinez was paying for gas when he came back out to his vehicle and was then randomly shot in the back of the head by Priester. Priester then fled the scene. Police later determined that the two did not know each other and it was a random attack.

Priester was already a convicted felon who was wanted on a parole violation. Authorities tracked him to New Jersey where he was eventually arrested.

Rojas-Martinez was a husband and father of three girls.

“This was a cold-blooded execution committed after Priester waited for the victim for hours at his place of business prior to following him to the gas station,” said ADA Jennifer Stevenson in a press release.

Priester was found guilty on charges of malice murder, felony murder, aggravated assault, possession of a firearm during commission of a felony, and possession of a firearm by a convicted felon.
