The 72-year-old man suspected of killing 10 people and wounding 10 others in a shooting at a dance studio in Monterey Park, California, Saturday had previously frequented the establishment, sources told CNN.The suspect, identified as Huu Can Tran, was pronounced dead following a self-inflicted gunshot wound Sunday as police swarmed a white van in Torrance, about 30 miles from Monterey Park, Los Angeles County Sheriff Robert Luna said.The shooting at Star Ballroom Dance Studio happened around 10:22 p.m. as the city's large Asian American community was celebrating Lunar New Year weekend. About 17 to 20 minutes later, an armed man showed up at a second dance studio in nearby Alhambra where authorities say people wrestled a gun away from him -- a firearm authorities ultimately used to ID the suspect, according to a law enforcement official with knowledge of the case. The semi-automatic weapon was traced to the suspect, which gave authorities his name and description, the official said. The mass shooting prompted a manhunt across the region, with a description of a white van seen leaving the Alhambra incident broadcast to area law enforcement agencies. On Sunday morning, officers in Torrance spotted a white van that matched the description."When officers exited their patrol vehicle to contact the occupant, they heard one gunshot coming from within the van," Luna said. "Officers retreated and requested several tactical teams to respond." Then -- as three armored vehicles blocked the van -- a SWAT team approached and found Tran dead inside, Luna said.As it remains unclear what motivated the shooting and a search warrant has been issued for Tran's home, the sheriff said it's too early to say whether the shooting could have been a hate crime and investigators are still working to determine whether any of the victims were known to the gunman.Here's what we know about the suspect.Suspect had once been a regular patron at the dance hall Tran had once been a regular patron at Star Ballroom Dance Studio, his ex-wife and a longtime acquaintance both told CNN.Tran's former wife, who asked not to be named due to the sensitivity of the case, said she met Tran about two decades ago at Star Ballroom, a popular community gathering place where he gave informal lessons. Tran saw her at a dance, introduced himself and offered her free lessons, she said. The two married soon after, she said.While Tran was never violent to her, she said he could be quick to anger. For example, she said, if she missed a step dancing, he would become upset because he felt it made him look bad. Tran filed for divorce in late 2005, and a judge approved the divorce the following year, Los Angeles court records show.Tran was an immigrant from China, according to a copy of his marriage license his ex-wife showed to CNN.It was unclear how frequently Tran visited the dance hall, if at all, in recent years.Video below: AAPI community in Massachusetts reacts to 'horrific' California shootingAnother longtime acquaintance of Tran's also remembered him as a frequent presence at the dance studio. The friend, who also asked not to be named, was close to Tran in the late 2000s and early 2010s, when he said Tran would make the roughly five-minute drive from his home in San Gabriel to Star Ballroom Dance Studio "almost every night."Tran often complained at the time that the instructors at the dance hall didn't like him and said "evil things about him," the friend remembered, adding Tran was "hostile to a lot of people there."The friend said he hadn't seen Tran in several years and was "totally shocked" when he heard about the shooting."I know lots of people, and if they go to Star studio, they frequent there," he said, adding he was "worried maybe I know some of" the shooting victims.Investigators are still looking into Tran's history, sheriff saysLuna told reporters Sunday that investigators are still looking into Tran's criminal and mental health history and serving search warrants.The Los Angeles County Sheriff's Department obtained a search warrant for Tran's home in a senior community in Hemet, California, according to Hemet police public information officer Alan Reyes.Records show Tran bought a mobile home in the community, which is in the outlying suburb about 85 miles east of Los Angeles in neighboring Riverside County.Video below: Police announce California mass shooting suspect is deadSeven years before buying the Hemet home, Tran in 2013 sold a San Gabriel home, which he had owned for more than two decades, property records show.Business records also show Tran registered a business called Tran's Trucking Inc. in California in 2002. But he dissolved the business about two years later, writing in a corporate filing that the company had never acquired any known assets or incurred any known debts or liabilities.Tran at times had worked as a truck driver, according to his ex-wife.The weapons authorities foundAuthorities are still working to determine how the gun allegedly used in the shooting was obtained.The weapon recovered from the Alhambra location was a magazine-fed semi-automatic assault pistol that had an extended large capacity magazine attached to it, the sheriff said Sunday.It was a Cobray M11 9mm semi-automatic weapon, which is designed to take 30-round magazines that allow for rapid fire without having to frequently change magazines, the law enforcement official with knowledge of the case told CNN.In response to a reporter's question, Luna said, "I believe the weapon that was recovered at the Alhambra location is not legal to have here in the state of California."Video below: Mass shooting suspect kills 10 near Lunar New Year festival in Southern CaliforniaA handgun was also discovered in the van with the suspect, the sheriff said.The suspect may have sought medical treatment shortly before the traffic stop in Torrance, law enforcement sources told CNN they believe. Police got a tip from an area hospital where a man fitting the description of the suspect came into the emergency room, seeking treatment for injuries consistent with having been in a fight.The person waited for a period and then left the hospital without receiving treatment, the sources said. The hospital notified authorities when staff saw the similarity to the wanted person. A short time later, police in Torrance stopped the van.

An 8-year-old girl is showing her love and passion for dancing, even after undergoing spinal surgery. She was supposed to take part in a big recital, but her parents say the dance studio isn’t allowing it. Pittsburgh’s Action News 4 reporter Marcie Cipriani spoke with both sides who are both demanding apologies. Watch the full story in the video player above. Lizzie Foster is hurt. She said she has been dancing for five years and that she was looking forward to her recital with her group at KD Dance Studio in Belle Vernon, Pennsylvania, but she said after a month in the hospital she came back to be pushed aside. “It was so emotional. Really sad,” Foster said. Lizzie is temporarily wearing a halo after surgery and a month-long stay in the hospital. Even while she was in the hospital, she would still dance. Lizzie’s mom Jennifer Foster said Lizzie’s doctor encouraged her to get back to dance and the owner of KD Dance said she was happy to have her back. Foster said inside the studio, her daughter was pushed to the side during recital practice and Lizzie said she felt left out and hurt by her instructor. KD Dance Studio owner Kim Duranti said that was not the case, that Lizzie asked to be on the side and that she has limited mobility right now. Also, there is no waiver from her doctor to participate. But Duranti said she was not keeping her from performing that day. Lizzie’s mother said she saw it and heard Duranti say that Lizzie wasn’t taking the stage for the recital she was working toward. Foster said it broke her heart to see the little girl who loves to dance so hurt. Duranti denies making Lizzie feel that way or putting her aside during practice. She said she would have allowed her to dance at the recital with proof Lizzie was medically allowed to participate. But Foster said she heard Duranti tell other parents she would not put Lizzie on stage with the halo.“I wanted to have an apology, that’s all I wanted and I wanted my daughter to have that apology because she never deserved that,” Foster said. Duranti said she wants an apology too, from the Fosters. For now, Lizzie will continue to dance. That’s one thing her mother and her dance teacher agree on.
