Updated 10:30 a.m Monday: The case has been reported as a suicide, according to coroner's Assistant Chief Ed Winter.  Rangel was found with a self-inflcited gun shot wound.

Original: A man suspected of shooting his mother in the leg, was found dead in his home by police after a five-hour police standoff.

40-year-old Shaun Rangel's body was found shortly after 8 p.m. by SWAT team members who had entered the home, according to Lt. Duane Allen of the Los Angeles County Sheriff's Department.  

A homicide investigation is now underway, though the likelihood is that Rangel killed himself, Allen said.

SWAT team members had used gas to fill the house and attempt to render Rangel unconscious.  They the entered the home and found his body.

According to Allen, detectives do not know when Rangel died yet, but they never were able to establish communications with him after arriving on the scene.  They were proceeding slowly, attempting to communicate with him before entering the house, but never heard him, saw him, or noticed any signs of life from the house.

According to Los Angeles Sheriff's Sgt. Cynthia Gonzales, Rangel allegedly shot his mother in the leg shortly after 3 p.m.  His mother and two other family members reportedly ran out of the house after she was shot, got into her red car and drove away as Rangel continued to fire at her.

The family drove the car a couple of blocks below the house, just south of the Lincoln and Altadena intersection.  For hours after the shooting, the car remained there with bullet holes visible (see image above).

The mother and the family members got out of her car and sought help, the sheriff's department said.  She was in stable condition as of 8 p.m. according to Gonzales.  The other family members remained at the crime scene.

Rangel then went back inside the house and locked himself in.
