Monterey Park shooting: New details on suspect, potential motive

Authorities searched for a motive for the gunman who killed 10 people at a Los Angeles-area ballroom dance club during Lunar New Year celebrations, slayings that sent a wave of fear through Asian American communities and cast a shadow over festivities nationwide. The suspect, 72-year-old Huu Can Tran, was found dead of a self-inflicted gunshot wound Sunday in the van that authorities say he used to flee after attempting to attack a second dance hall. The mayor of Monterey Park said Tran may have frequented the first dance hall that he targeted.
