The suspect's wife was hospitalized with serious wounds and released, said Lt. Eddie Hernandez, of the Los Angeles County Sheriff's Department.
The boys' uncle may have forced his way inside while the boys' parents were away tending to the suspect's wife at the hospital, Hernandez said.
FBI officials confirmed to detectives that he was on a plane to China.
