San Rafael woman arrested for alleged fatal stabbing of her mom on livestream: police

SAN RAFAEL, Calif. -- A San Rafael woman who was arrested after she allegedly fatally stabbed her mother Monday afternoon allegedly filmed the act and broadcast it on social media, according to police.

Shortly before 5 p.m. Monday, San Rafael police officers responded to Cresta Way after they were alerted to multiple reports of a physical fight and stabbing at an apartment in the complex. Upon arrival, they were directed to an apartment's rear balcony where they allegedly saw Tonantzyn Oris Beltran, 28, on a balcony holding a knife in her hand, standing next to a stabbed female victim with "her clothes soaked in blood," police said.

Police said Beltran was not readily responsive to the officers' commands and directions. As officers were confronting Beltran from the balcony, another team of officers forced their way into the apartment through the front door and immediately took her into custody.

Firefighters were able to give first aid to the victim, who was then sent to a hospital. However, she died due to her extensive injuries, police said.

According to police, the victim was identified as Beltran's 55-year-old mother. They said they are looking into a possible motive for why the suspect allegedly stabbed the victim.

As the investigation evolved, San Rafael Police said the stabbing was allegedly filmed by Beltran and broadcast on Facebook Live. Authorities reached out to Facebook's parent company Meta to get the footage taken down and it was, police said. Initial calls about the stabbing first came into police from witnesses at the scene and viewing it on Facebook.

San Rafael police said Beltran has produced content on many social media platforms and even filmed herself in the Santa Rosa Police Department's lobby on Monday. Both departments are working together to determine what occurred, according to police.
