Police have identified the suspected gunman as 72-year-old Huu Can Tran, and confirmed he shot and killed himself inside a white van officers had surrounded earlier on Sunday.
Corporation records obtained through the State of California showed that Tran once registered a corporation called Tran’s Trucking Inc.
Its registration terminated two years later.
He was living in San Gabriel, California, at the time, according to the 2002 filing.
His ex-wife and friends told CNN Tran used to frequent the Star Ballroom Dance Studio where the mass shooting occurred and described him as quick to anger and irritable.
The ex-wife was not identified by CNN, which reported that she said he was never violent but angered quickly, including when she “missed a step dancing.” She thought he had lost interest in her, and he filed for divorce in 2005, CNN reported.
According to CNN, Tran “was an immigrant from China.”
Huu Can Tran was searching for his wife, witness says
Police have not revealed a motive for the shooting, but a witness has told CBS the gunman came to the Monterey Park dance studio to find his wife.
She told the outlet – that he opened fire on the ballroom without saying anything.
“He found his wife there,” the witness, who wanted to remain anonymous, said.
“He started to shooting everybody… when they dance.”
The witness could not confirm that the gunman was the same man authorities had distributed a photo of, but said his clothes seemed similar.
Victims are believed to be in their 50s and older
LA County Sheriff Robert Luna says he does not have the ages of the victims, but said they “are not in their 20s and 30s, and seem to be in their 50s, 60s and maybe some even beyond”.
