MONTEREY PARK, Calif. — The search for the motive behind the shooting massacre that killed 11 people at a Los Angeles-area dance hall led police to a mobile home community as they probed the past of the 72-year-old suspect Monday and his relationship to the ballroom.

Sheriff’s deputies from Los Angeles County searched the home in a gated senior community where Huu Can Tran lived in the town of Hemet, an hour’s drive from the scene of the crime in Monterey Park, Hemet police spokesperson Alan Reyes told The Associated Press.

Monterey Park Police Chief Scott Wiese said he wasn’t aware of the search results or if Tran, who died of a self-inflicted gunshot wound, left behind any note indicating what drove him to shoot up the dance hall.

“We all want answers to questions that we may never have answers to,” Wiese said. “That’s kind of the enigma of this. I know that my individual officers would like to know why. I know the families want to know why. The why is a big part of this. The problem is, we may never know the why.”

Tran had visited Hemet police twice this month to report he was the victim of fraud, theft and poisoning by family members a decade or two ago in the LA area, Reyes said. Tran said he would return to the station with documentation but never did.

He was found dead Sunday in the van that he used to flee after attempting to attack a second dance hall, authorities said. The mayor of Monterey Park said Tran may have frequented the first dance hall that he targeted, and his ex-wife told CNN she had met him there and he offered her free lessons.

The death toll rose to 11 Monday after health officials announced that one of the 10 people wounded had died, the LA County Department of Health Services said.

Officials did not disclose any information about the 11th fatality, but all except one of the others were 60 or older, according to information released Monday by the Los Angeles coroner’s office providing the first identifications.

My Nhan, 65, and Lilian Li, 63, were the first two women named. Two other women were in their 60s, and one was in her 50s. Three men were in their 70s, and two in their 60s were also killed.

Nhan’s family said in a statement that she was a loving person whose kindness was contagious, and was a regular at the Star Ballroom Dance Studio.

“It’s what she loved to do. But unfairly, Saturday was her last dance,” the family said. “We are starting the Lunar New Year broken. We never imagined her life would end so suddenly.”

Authorities have shared little about Tran.

Los Angeles Superior Court records show he was married in 2001 and divorced five years later, citing irreconcilable difference. The couple did not have children, said they had no community property and neither side had to pay alimony.

In the uncontested case, Tran noted in a filing that he could not get away from work to attend any court hearings, though he did not disclose where he worked or what he did.

His ex-wife told CNN that they married soon after they met at the dance hall. While she is named in court papers, she asked not to be identified because of the sensitivity of the case.

She said he would become upset if she missed a step dancing, but was never violent toward her.

Tran eventually moved from the San Gabriel Valley, a melting pot for Asian immigrants, and settled in Hemet, a low-income community of many retirees 75 miles east of Los Angeles in Riverside County.

Tran lived in The Lakes at Hemet West, a gated community off a busy road with a view of snow-covered mountains. The development boasts of amenities including a 9-hole golf course, a shuffleboard court and a dance floor. Properties listed for sale ranged from $45,000 to $222,000.

Hemet police had no records of any incidents involving Tran in the community or calls for service at his home, Reyes said.
