According to the Los Angeles County Sheriff's Department, deputies responded to the home near Dawn Haven and Colima roads around 5:30 a.m. Monday. A 911 call came from within the home, but it's unclear what led up to the deadly stabbing.
The source said the the suspect confronted deputies when they arrived, and that's when they opened fire in the front yard. The suspect died at the scene, but it's unclear if he was still armed at the time.
Lt. Daniel Vizcarra said the son used a large knife. The ages and identities of both the suspect and his father have not been released.
One man who stumbled upon the police tape while on his morning walk Monday told Eyewitness News he's lived in the neighborhood for almost 40 years and was surprised to hear what happened.
"This is a pretty quiet neighborhood. We have hardly ever had any problems like this," said Thomas Chao. "Almost 40 years and this is the first time I've seen this many police officers in this area."
