Investigators believe 35-year-old Jonathan Misirli shot those men and was captured on video walking out of a wooded area after the murders.
Detectives believe Misirli had been living in a well-concealed area surrounding the Griffith Park Observatory at the time of the shootings.
Misirli was arrested just south of the park on North Vermont Avenue. He was booked on suspicion of murder and is under a no-bail order.
