Around shortly before 1 a.m., gunfire broke out at a residence in the 10900 block of Bartlett Avenue where about 30 people were gathered for a birthday celebration. Twenty-year-old Maqwan Allen of Rancho Cucamonga suffered critical injuries, was driven to a local hospital, and was later pronounced dead.

Another 20-year-old, Derrick Irutingabo of Arizona, was found dead at the scene. Five additional people between ages 14 and 40 were shot and hospitalized; their conditions were not disclosed.
