A 34-year-old mother of five was allegedly stabbed to death by her boyfriend in Simi Valley, police said.

Simi Valley Police responded to a call of domestic violence on Friday at 830 California Avenue.

The reported party stated that her mother was being stabbed by her boyfriend who she resides with, according to police.

When officers arrived at the home they found the victim, Jessica Tinoco, with multiple stab wounds in the face, chest and abdomen. Tinoco was transported to a nearby hospital where she succumbed to her injuries.

The accused attacker, 34-year-old Raymond Rivas, was arrested and booked into Ventura County Main Jail on charges of murder. Rivas was on Post Release Community Supervision at the time of the incident and was placed on a hold for violating probation.

An old oak tree rooted in controversy was assigned a historical landmark on Tuesday following a unanimous vote from the LA County Board of Supervisors.

Developers in 2002 were poised to knock down the oak tree “Old Glory” to make way for a subdivision in the Santa Clarita Valley.

The tree was eventually saved with the help of efforts from one man.

Environmental activist John Quigley spent 71 days on a wooden platform in the tree in protest of the city’s removal plan. Quigley would soon learn not everyone agreed with him.

“The windstorms, all the threats, the gunshots, the exploding mailboxes,” said Quigley.

When asked if it was worth it, Quigley’s response was “absolutely.”

A compromise was met and the tree was carefully removed from its original location and then replanted at its current home at Pico Canyon Park.

After 22 years since Quigley climbed the tree, Old Glory has become an LA County Historic Landmark, giving it protection from ever being targeted again.

“That tree is an incredible teacher, and I think will continue to teach now, with this landmark status,” said Quigley. “Never underestimate the power of one person to create a sea of change in society.”

Arborists believe the tree’s life dates back to the 1600s.

Police are investigating the events that led up to a fatal stabbing Saturday in Beverly Hills.

Detectives say initial reports indicate there was a confrontation between two men near the intersection of Spalding Drive and Charleville Boulevard.

A witness who asked not to be identified tells NBC4 that the injured man police arrested allegedly tried assaulting a father with a little girl near that same intersection.

“He had a baby in his arm and being attacked by an assailant was clearly a situation that we couldn’t just drive away from, so we pulled up right in front of them,” said the witness, who intervened. “He was not present, he was having some kind of psychotic break, and so it was kind of scary.”

The witness says as soon as he pulled over his son jumped out to help the father and child – he then saw the man with a deep cut on his face turn his attention to his car and said he tried grabbing his dog.

“I reached back, grabbed her, and then was pulling her back, but he wouldn’t let go, so I was pulling her, he was pulling her, and then I started punching him because I was yelling at him to get out of my car.”

The witness says during this time his car slowly rolled into a yard on Spalding– and saw the injured man stumble away towards a nearby home. He added that he did not see how the fatal stabbing happened.

The man with the stab wound was taken to a hospital where he later died, according to authorities.

Police have not released the identity of that man and say the other person involved in the confrontation is cooperating with investigators.
