A 12-hour manhunt for a gunman who killed 11 people and injured almost as many at a Monterey Park, California dance studio Saturday night ended with the arrest of 72-year-old Huu Can Tran. Brandon Tsay, who confronted the suspect in the lobby of a dance hall run by his family, was praised for his heroic actions by Sheriff Robert Luna. Monterey Park Police Chief Scott Wiese described the scene as "chaos and extensive carnage" when officers arrived, and the motive behind the attack is still under investigation.
