Adam Dimmerman, 47, was already in custody when police charged him with murder.
The assault victim, who sustained minor injuries, and other residents in the area pointed the officers at Dimmerman, who was arrested without incident, police said. An ax and knife were found at the scene.
An hour later, patrol officers responded to another call in Encino after firefighters located an elderly man with multiple cuts and bruises in his home.
The man, who police did not name in their news release, was pronounced dead at the scene.
Police said Friday that Dimmerman had been charged with the murder of the elderly man. He was also charged in the first assault. Police did not provide a motive.
It was not immediately clear whether Dimmerman had a lawyer.
“I thought he fell. I had no idea. They told me he fell in the garage and my cousin came home and found him,” Shakib told KABC. “I just thought he slipped and fell because he was an older man. I had no idea there was a man with a machete running around killing people. ‘
Mahboubian and his wife lived in Alonzo Place, a street in Encino, for 30 years, Shakib said. He was an immigrant from Iran who moved to the US “decades and decades ago”.
“My wife was horrified to hear that he had been killed by some ax-wielding psychopath,” Shakib said. “He must have been degenerate.”
Dimmerman is charged with murder and is currently on bail set at $ 2 million.
