Rene Alejandro Lupian, 22
Rene Alejandro Lupian, a 22-year-old Latino, was fatally shot on Wednesday, Nov. 7, in the 900 block of South Concourse Avenue in East Los Angeles, according to Los Angeles County coroner's records.
Investigators believe that the shooting stemmed from a robbery, and that the attacker fled with Lupian's dark-colored Jansport backpack, said Los Angeles County Sheriff's Det. Theo Baljet.
His older sister, Christian Lupian, said she thinks the robber might have been attracted by her brother's necklace, which was lying on the ground when officers found him.
"I think he tried to snatch it, rip it off him," Christian said. "It was gold, with a cross, something our grandma gave to him before she passed away six months ago. I would tell him sometimes, 'Dude, don't wear that out,' but he was so proud to wear it. It really meant a lot to him."
