Investigators on Monday released new surveillance images of three men suspected of running over and killing a 31-year-old woman who tried to stop them after they assaulted her boyfriend in Lancaster, officials said.

The incident unfolded at a residential complex around 8:20 p.m. Friday on the 44000 block of 15th Street West.

The trio tried to rob someone at gunpoint. They allegedly pistol-whipped the victim, who was knocked unconscious, and fled in a vehicle, officials said.

The victim’s girlfriend, Samantha Mena, then chased after the suspects, the Los Angeles County Sheriff’s Department said in a news release.

“During the course of this incident, the suspects entered their vehicle and ran over the victim as they fled the scene,” the agency said.

Responding deputies found Mena badly injured and lying in the street. She was taken to a hospital, where she was pronounced dead.
 
The men fled the scene in a light colored sedan and have yet to be found. Officials initially said there were two robbery suspects.

It’s unclear what the men were targeting in the alleged attempted robbery.

On Monday, the Sheriff’s Department released surveillance images of the three suspects, in hopes that members of the public could help identify them.

They were all described as being Black men between 20 to 30 years old.

“The persons pictured in the flyer are responsible for her murder. Detectives are seeking to identify and locate them,” officials said in releasing the images.

Relatives described Mena as a loving person who was going to school while working two jobs.

“She was doing something for her life, so what hurts me is that these individuals, that were not doing nothing for their lives, took her life,” Mena’s mother, Celia Mena said.

In an interview, Mena’s parents said they want justice for their daughter.
