Three people were shot and killed, and four others injured, at a party held on Saturday January 28 in a luxurious residence near Beverly Hills, an upscale district of Los Angeles.
This drama occurs while California is still marked by two shootings that left 18 dead in total on January 21 and 23.
The three victims were found in a vehicle parked outside.
The four injured, two of them seriously, were hospitalized on Saturday.
The house where the party was held is located in one of the wealthiest areas of Los Angeles, where multimillion-dollar homes compete in pomp.
Investigators believe that a "
gathering
" took place there but do not yet know the nature, said police officer Bruce Borihanh.
