A neighbor who didn't want to be identified spoke with Eyewitness News, calling the incident "frightening."
"It's very frightening. It's generally a quiet neighborhood," she said. "It's sad. It's very sad. We've been here for about 20 years and my heart breaks for the family across the street."
She said the family was always happy.
"They would literally have like a flat iron barbecue outside. The lights would be up and happiness, happiness, happiness - always. So this is very shocking."
Police are searching for the suspect and have not released further details on the case. Anyone with information is urged to contact LAPD.
