Luna added that the motive remained unclear for the attack. The weapon suspected to have been used was identified as a magazine-fed semi-automatic assault pistol, which was also found in the van.

“I still have questions in my mind, which is: What was the motive for this shooter? Did he have a mental illness? Was he a domestic violence abuser? How did he gets these guns and was it through legal means or not?” Congresswoman Judy Chu said.

The manhunt came after the gunman killed 10 people at a ballroom dance studio late Saturday amid Lunar New Year celebrations in the predominantly Asian American community of Monterey Park. He likely tried and failed to target a second dance hall, authorities said.

The shooting sent a wave of fear through Asian American communities in the Los Angeles area and cast a shadow over Lunar New Year festivities around the country. Other cities sent extra officers to watch over the celebrations.

“The community was in fear thinking that they should not go to any events because there was an active shooter,” said Rep. Chu, D-Calif., adding that she wants residents to now feel secure.

“Feel safe,” she said to residents during a press conference late Sunday. “You are no longer in danger.”

Luna said the shooting at the Star Ballroom Dance Studio in Monterey Park left five women and five men dead and wounded another 10 people. Then 20 to 30 minutes later, a man with a gun entered the Lai Lai Ballroom in nearby Alhambra. The suspect entered the Alhambra club with a gun, and people wrested the weapon away from him before he fled, Luna said.

The van was found in Torrance, another community home to many Asian Americans, about 22 miles from that second location. Law enforcement officials swarmed and entered the van after surrounding it for hours before going in. A person’s body appeared to be slumped over the wheel and was later removed from the vehicle.

The massacre was the nation’s fifth mass killing this month.

President Biden and Attorney General Merrick Garland were briefed on the situation, aides said. Biden said he and first lady Jill Biden were thinking of those killed and wounded, and he directed federal authorities to support the investigation.
