Three people are dead and two others are injured after three separate shootings within the span of an hour Sunday morning, and the Los Angeles Police Department says the attacks may be related.

LAPD Officer Liliana Preciado says a 20-year-old woman died in the first shooting at 5:50 a.m., in the San Fernando Valley.

Two others were injured.

Forty-five minutes later, LAPD responded to a call in Sylmar and found a man dead at the scene.

Ten minutes later, a third woman was shot in the head and died.

Preciado says one of the victims had special needs and was possibly autistic.

The suspect's vehicle is described as a tan or light-colored SUV with tinted windows.

Police believe the shootings may be related.
