Joshua Simmons of Long Beach was fatally shot Friday night while attempting to buy a cell phone from someone he met on an online marketplace, and on Sunday, friends and family gathered to remember the 15-year-old.

Vannarith Im, Simmons’ uncle, said his nephew was fatally shot in a place where the community often plays, which police said was in the 1000 block of Via Wanda.

“He thought he was safe … Nobody saw this coming,” Im said.

Los Angeles resident Jose Bustamante Cardenas, 24, was arrested in the shooting, and he is being held in lieu of $2 million bail, jail records show.

Cardenas contacted police and admitted to the shooting, according to the Associated Press.
