The shooting happened near where thousands of people had attended a Lunar New Year celebration.
MONTEREY PARK, Calif. — A gunman killed 10 people at a ballroom dance studio amid a day of Lunar New Year celebrations and then may have tried - but failed - to target a second dance hall, authorities said Sunday. An urgent search was underway across the Los Angeles area for the suspect.

Los Angeles County Sheriff Robert Luna said that 20 to 30 minutes after the shooting at the Star Ballroom Dance Studio in Monterey Park late Saturday - which left five women and five men dead and another 10 people injured - a man with a gun entered the Lai Lai Ballroom in nearby Alhambra. Luna said it’s still unclear whether the events are connected.
