Woman's Mother, Sister Kill Her Ex-boyfriend with Kitchen Knife after Break In—'Within Their Right' Say Police

A mother and daughter who killed a man after he broke into their Los Angeles County home and started attacking his ex-girlfriend will not face any charges, police have confirmed.

The Los Angeles County Sheriff's Department said they are continuing to assist the South Pasadena Police Department with their investigation into the death of a man in his forties on Saturday morning.

South Pasadena officers were called to the 500 block Five Oaks Drive, South Pasadena, following reports of a domestic violence incident in progress.

When officers arrived at the scene, they found the front window of the property shattered and could hear the sound of a woman screaming coming from inside.

The officers entered the building through the broken window and found a white male suspect in his forties stabbed and beaten.

Emergency services arrived at the scene and pronounced the man dead. The suspect was later identified by the Los Angeles County coroner's office as 40-year-old Justin Goss of Glendale, California.

During the investigation, it was found that Goss broke into the residence to attack his estranged girlfriend. While the suspect was in the processes of beating and choking the female victim, the mother and her adult sister came to her aid. During the struggle, the suspect was stabbed with a kitchen knife and beaten with a golf club.

"They tried to pull him off, and it didn't work; he was too strong," said Lt. Barry Hall, from the Los Angeles County Sheriff's Department, reported KTLA. "So they had to resort to using weapons.

"They were well within their right to act in defense of their sister and daughter," Hall said.

The female victim, who has not been identified, was transported to the local hospital and treated for facial injuries and has been released.

Under California state law, a person is within their legal right to use fatal force in their own home if they are defending themselves or anyone else within the property from someone who had entered the home intending to commit an act of violence.

The Los Angeles County Sheriff's Department has been contacted for further comment.
