Police are seeking a man considered armed and dangerous after he was caught on video fatally shooting his former girlfriend outside a Pacoima home, officials said.

Around 9:35 a.m. Wednesday, officers responded to the 9000 block of Bartee Avenue regarding a shooting, the Los Angeles Police Department said in a news release.

They located a victim, identified as 35-year-old Karen Ruiz, who had sustained multiple gunshot wounds. Paramedics responded and pronounced the woman dead at the scene, according to LAPD.

A preliminary investigation by homicide detectives revealed that the victim’s former boyfriend, identified as 46-year-old Herbert Nixon Flores, fired multiple shots at the woman with a semi-automatic handgun, police said.

The shooting was caught on Nest video footage, in which the man can be seen pulling up behind a vehicle in a driveway, as the victim appears to be retrieving something. When the woman spots him, she screams and starts running away, towards the front door of the home and calling out for help. The man can then be seen chasing her and shooting her.

Several shots can be heard, and the victim is heard yelling for help. The screaming and crying of a child is audible, and a man’s voice from inside the home, saying, “he killed her.”

The suspect shot the victim in the presence of their young child, LAPD said.

The 3-year-old is now safe with family members, according to police.

Flores had allegedly been stalking and threatening Ruiz for months, officials said.

“The relationship was violent,” said LAPD Detective Sharon Kim. ”She had several reports made against him over the years and most recently she took out a restraining order against him due to some violent acts he committed against her.”

Flores is considered armed and dangerous and, if seen, the public is urged not to confront him or attempt to apprehend him but to contact law enforcement immediately, police said.

“He has a violent criminal history. He is an MS-13 gang member,” Kim said.

Flores is a Hispanic male with black hair and brown eyes. He is about 6 feet, 1 inch tall and weighs around 220 pounds, according to police.
