Authorities reported finding a 17-year-old in the parking lot with gunshot wounds. He was taken to the hospital via Life Flight, where he was later pronounced dead, officials said.
A preliminary investigation revealed that the two were meeting to complete an online sale when the teenager allegedly tried to rob the seller, prompting the man to open fire, Sheriff Ed Gonzalez said.
The alleged shooter stayed at the scene and told officers he was trying to sell the 17-year-old a pistol when the teenager tried to steal the gun.
