The coroner’s office confirmed the names of all four people killed in a shooting at a Jan. 23 party in Inglewood that also left one person wounded.

Breahna Stines was celebrating her 20th birthday at the party along with her sister, Marneysha Hamilton, 25, and Teron Whittiker Jr., 21. They died at the scene and Jayden Griffin, 21, died at a hospital.

Firefighters and paramedics were sent to the 1300 block of Park Avenue at 1:43 a.m. Sunday, according to a Los Angeles County Fire Department dispatcher. None of the victims lived there. It was a short-term unregulated rental, according to Inglewood Mayor James Butts.

The surviving victim was gang-affiliated, Butts said. He was last reported in critical condition but was expected to survive.

Butts said there were multiple shooters, at least one of whom used an assault weapon. The other weapon involved was a handgun, Butts said. 

“These are sociopathic killers that have to be sequestered from society,” the mayor said at a Sunday morning news conference.

No suspect descriptions were immediately available.
