A Beverly Hills mansion was rented on AirBnb for a private event. Dozens and dozens of people attended an "unmasked" party at the home, but the event turned to tragedy as shots rang out.The shooting at the out-of-control party left one dead and three wounded and fighting for their lives. TV news helicopters spotted dozens packed into the house earlier in the day. Neighbors called the LAPD to report the party, but police officers said they couldn’t do anything because the party was on private property. However, that changed when shots rang out around midnight, and police moved in on the scene.
