MONTEREY PARK, Calif. —The suspected gunman wanted for killing 10 people and wounding at least 10 more at a dance club Saturday is dead after shooting himself and has been IDed as a 72-year-old man

The alleged mass murderer, identified as Huu Can Tran, turned a gun on himself inside a cargo van following a stand-off with law enforcement, Los Angeles County Sheriff Robert Luna said during an evening press conference outside Monterey Park City Hall.

The sheriff said Tran, who’s accused of shooting up a Monterey Park ballroom following a Lunar New Year celebration, acted alone and officials are still investigating a motive.
