When asked whether authorities had discovered a motive in the Monterey Park attack, Luna said the gunman, Huu Can Tran, had sent a “manifesto” to law enforcement that was still being examined. Tran, 72, opened fire the night of January 21 at a Lunar New Year celebration at a dance studio in Monterey Park – in a majority Asian community just east of Los Angeles. The assailant then went to a dance studio in nearby Alhambra where a man wrestled a gun from him, the sheriff has said.
In January, the sheriff said the gunman used a 9mm semi-automatic MAC-10 pistol with an extended large-capacity magazine. The disarmed weapon was traced to the suspect and provided authorities his name and description, Luna added. The gunman was “very familiar” with the dance studio where the shooting took place, Los Angeles County District Attorney George Gascón told CNN after the shooting. “There is certainly the appearance that this was targeted,” he added.
