On Sept. 16, McCloud was convicted of two counts of second-degree murder for the slayings of Breon Taylor, 15, of Los Angeles, and Dennis Moses, 17, of Long Beach, along with 46 counts of assault with a firearm.
His co-defendant, 22-year-old Jonzel Stringer of Bellflower, was also convicted and will be sentenced on Nov. 16.
Prosecutors say Stringer got into a fight with gang rivals at the party. McCloud and Stringer then fired into the crowd, where prosecutors say 46 partygoers were in the "kill zone" during the gathering at the Masonic Hall at 5900 block of Parkcrest Street. A 17-year-old boy was shot in the leg.
Prosecutors say the shots were fired from a 9mm semiautomatic gun in the parking lot and targeted the hall, where more than 400 people had shown up for a party originally intended for 100 guests.
