A makeshift memorial has been set up at the scene of the shooting where two people died, and three were seriously injured.
Police say it all started when the shooter approached two people sitting in a car just before 11 p.m. Sunday.
He shot both people inside, 21-year-old Brenda Aguilar and Jonathan Plasencia.
Aguilar died at the scene, and Plasencia was transported to a local hospital where he also died.
As the gunman took off, investigators say he opened fire on three women who were sitting on their porches who may have been witnesses.
The three women were taken to hospitals. Two women sustained critical injuries, and the third woman was shot in the foot and was released Monday morning.
People in the neighborhood are terrified after the incident.
A woman who was on the porch spoke to Eyewitness News, but did not want to be identified.
"We didn't see nothing. We didn't know. We thought it was just firecrackers, kids playing," she said.
Aguilar's sister Diana Lopez sobbed as she said Aguilar had celebrated her 21st birthday just last week.
"I would like whoever saw anything to tell the cops so that the people can be found," Lopez said.
Anyone with information is urged to call the LAPD Newton Division at (323) 846-6547.
