Prosecutors say a teenager accused of killing his girlfriend's mother and stepfather and then shopping for a Halloween party with one of the bodies still in the car has been convicted of murder and now faces a possible life sentence.
Compton jurors deliberated for just over an hour before finding 18-year-old Giovanni Gallardo guilty of two counts of murder, according to the Los Angeles Times.
Gallardo was 16 at the time of Gloria Villalta and Jose Lara's killings in 2011, but he was tried as an adult.
Cynthia Alvarez, who was 15 at the time, was convicted by a separate jury after testifying she and Gallardo stole the victims' jewelry and truck parts to fund a Halloween party.
The two went to a party supply store with her dead mother's body in the back of the car.
The decomposing bodies were found buried in shallow graves days after their killings.
