The two men, identified by neighbors as Tom Boulet and Ken Coll, were found by officers with multiple stab wounds. They were rushed into surgery and are in critical condition, but they are expected to survive.

“It’s shocking, you never think about it,” neighbor Andre Saab said. “As a dad, my own son to stab me? Wow.”

The suspect – 21-year-old Matthew Boulet, who is home from college – was found inside the house and allegedly admitted to stabbing his fathers to officers. His face bloody, he was taken into custody.

A pocket knife was recovered, police said. Matthew Boulet also suffered an injury to his hand during the stabbing.

Authorities are looking into whether mental illness may have been a factor.

“He was very nonchalant when he said he had stabbed his two fathers and that he suffered a wound while doing so,” Los Angeles police Lt. Mike Kozak said. “He was very calm about it.”
