Man shoots and kills his brother for allegedly attacking their mother at home in Beverly Grove area

LOS ANGELES (KABC) -- A man shot and killed his brother who had allegedly attacked their 80-year-old mother with a baseball bat at her home in the Beverly Grove area.

The shooting was reported just before 1:30 p.m. Friday near Alfred Street and Oakwood Avenue, according to the Los Angeles Police Department.

The 61-year-old suspect used a baseball bat to break into his mother's home and then attacked her, police said.

The suspect's brother arrived at the scene and witnessed the attack, police said.

"When he arrived, he saw his mother on the floor. He saw his 61-year-old brother on top of her, choking her," LAPD Detective Samuel Marullo said.

At that point, the suspect's brother fired a warning shot and later fatally shot his sibling with a shotgun.

LAPD says the suspect made threats the night before and left the house before police arrived. It does not appear he lived at the home.

Police initially arrested the suspect's brother, but were set to release him after determining the shooting was a justifiable homicide.

The woman was taken to a hospital in stable condition.

Detectives continue to piece together what motivated the attack.
