4 dead, 1 injured in 'targeted ambush' on Los Angeles-area home

At least four people are dead and another was in critical condition after multiple gunmen, at least one armed with an assault-type rifle, opened fire on a home.

Four people are dead and another is in critical condition after multiple gunmen, at least one armed with a semi-automatic rifle, opened fire at a Southern California home Sunday morning in what authorities said appeared to be a "targeted ambush."

"These are sociopathic killers that have to be sequestered from society," James Butts, the mayor of Inglewood, said at a news conference Sunday following the quadruple homicide.

The shooting erupted at about 1:30 a.m. in a residential neighborhood of Inglewood, about 10 miles southwest of downtown Los Angeles, according to the Los Angeles County Fire Department.

Three of the shooting victims were pronounced dead at the scene, fire department officials told ABC station KABC in Los Angeles. A fourth victim died en route to a hospital, fire officials said.
