monterey park was considered the first suburban chinatown and is home to a predominantly asian american community, one now deeply shaken by a shooting rampage here during a lunar new year celebration. tonight one more person has died from gunshot wounds. that brings the death toll to 11. nine others were wounded. police say by a 72-year-old gunman who later took his own life, but not before he was forced out of a second dance hall by a young man who courageously disarmed him, all of it caught on surveillance video. i spoke to that man, brandon, who is being called a hero tonight about how his quick actions likely saved many more lives. this as we're learning more about the victims and as we speak to the community about their stories of survival. tonight the search for answers. another american community reeling after a night of celebration was shattered by a hail of bullets. the first emergency calls flooding in at 10:22 p.m. on

saturday. >> additional units requested. multiple victims, gunshot wounds. >> a gunman opening fire at the dance studio in monterey park. when officers arrived on scene, they observed numerous individuals pouring out of the location, screaming. >> you have 10 unresponsive inside. >> tonight at least 11 people are dead, and 9 injured. and now we're hearing stunning survival stories from inside. sally was there with her dance partner of 15 years. >> we are so happy. everything happy at the start. >> lots of people dancing. >> like 50 people. >> then the shots rang out and they both jumped under a table. she told us her partner was shot in the back and killed. when did you realize that your partner had been hit? >> i didn't realize until i had blood on my hand. >> and it wasn't yours? >> i was so scared. i thought i got shot. >> she says he died shielding her from the bullets, saving her

life. >> he was trying to cover you. >> yes. he tried to cover us. we were so scared. >> and more accounting two miles away inside the lai lai ballroom and studio in alhambra, where the suspect showed up 20 minutes after his deadly rampage. today i spoke with brandon seen on this surveillance video bravely taking on the gunman, disarming him before he could unleash more terror. how did you decide what to do? >> there was a moment i actually froze up because i was -- i had to believe that i was going to die. like my life was ending here at that very moment. but something -- something amazing happened. a miracle, actually. he started to try to prep his weapon so he could shoot everybody. but then it dawned on me that this was the moment to disarm him. i could do something here that could protect everybody. in one shove, i kind of just pushed him

away and then quickly aimed the gun at him and shouted, go away or i'm going to shoot. get out of here. go! >> are you pointing the gun at him as you're saying this? >> yes, i was. >> police are hailing brandon as a hero. did he say anything during this encounter? >> no. his facial expressions, eyes did most of the talking. >> what did those eyes tell you? >> he told me he want to do harm. like he was a troubled individual trying to do harm to others, make people feel the pain he was feeling. >> the gunman fled the scene. then after an hour's long man hunt, police locating this white van. >> they're breaching the van. >> at 12:52 p.m., a swat team broke the van's windows, finding the suspect, 72-year-old huu can tran with a fatal self-inflicted gunshot wound. a handgun was found inside, while a semiautomatic pistol with an extended magazine was recovered from that second dance hall.

and the suspect's motive still a mystery. the mayor saying he may have frequented one of the dance studios. >> the problem is we may never know the why. >> tonight few answers for those grieving in monterey park, a center of southern california's chinese community. and now we're learning more about the 11 people whose lives were stolen. all in their 50s, 60s and 70s. including 65-year-old my nhan. her family writing, she spent so many years going to the dance studio. it's what she loved to do. but unfairly saturday was her last dance. her warm smile and kindness was contagious. my nhan was our biggest cheerleader. so the key question tonight, what drove the gunman to target these two dance halls, different halls.

kate snow on the investigation as we learn more about the shooter's background. >> reporter: tonight new details about the alleged shooter huu can tran as police learn more about his past. >> we recovered one .308 caliber rifle, numerous electronic devices such as cell phones, computers, et cetera. items that lead us to believe the suspect was manufacturing homemade firearm suppressors. >> multiple law enforcement tells nbc news suggests a personal motive rather than terrorism or a hate crime. they're examining whether the crime may have been directed at a star ballroom or as a business. the gunman targeted two ballrooms, heading to a second location after killing 11 people. detectives believe he had frequented most locations according to the l.a. times. >> mass shooters are inside the places where they target. so school children target schools.

workplace employees target their place of employment. it is often because you have an existing grievance with that location. and also because these are places that you know the best. >> reporter: the suspected gunman met his former wife at the star ballroom. his ex-wife showed cnn a copy of their marriage license indicating he was an immigrant from china. she told the network he was a truck driver at the time and could be quick to anger. the two divorced in 2006. about a year ago, he moved to hemet, california, 70 miles away. police executed a search warrant last night at the home where neighbors described him as quiet. >> he seemed like a nice guy. i mean, he didn't -- he wasn't like somebody i would be afraid of. >> reporter: we also learned the suspected gunman was known to law enforcement, visiting the hemet police department lobby two weeks ago alleging past fraud, theft and poisoning involving his family, but never providing any evidence. >> he has a limited criminal history with an arrest in 1990 for an unlawful possession of a firearm. >> and cate joining me here.

one of the many on ser stragss i've heard is this gunman was older than those we typically see do these type of crimes. >> reporter: 72 years old, lester. and the typical median age for a gunman in a mass shooting in this country is 32 years old. there is only one time we know of in the past where someone in their 70s committed a crime like this, and that was over 40 years ago. >> kate snow, thank you. also tonight, we can tell you that as you heard this all happen as the community celebrated the all important lunar new year as hate crimes against asian americans have been on the rise. cathy park joins me now. what have members of this tight knit community been telling you? >> reporter: well, lester, as you could imagine, many residents say they have been taken by this senseless attack. this happened during one of the most joyous times of the year. tonight, the joy of ringing in the lunar new year gripped by tragedy in monterey park. >> heart broken that

it happened on a day that people are supposed to be celebrating. >> reporter: considered the first suburban chinatown and a safe space for immigrants, the streets offer a flavor of the culture that exists in this predominantly asian community. here traditions date back centuries, including the most important of them all. how sacred is the lunar new year for the asian community? >> it's our holy day. >> they're really important, yeah. every year we celebrate. >> reporter: the mass shooting canceled festivities that typically attract tens of thousands of visitors for one of the largest lunar new year's celebrations in southern california. other major cities including new york, san francisco and seattle heightened ri resources for their own celebration. >> we're living in america, and every time we go out, there is that threat. >> reporter: law enforcement sources say the 72-year-old asian gunman's motives were personal. still, the violence brought up memories of attacks targeting asians. >> i think everyone was on edge that this was going to be

another horrific hate crime against asian americans. >> reporter: recent data show only half of aapis feel safe going out. and 65% worry about the safety of family members and elders. he lives and works in monterey park. do you think this shooting will change the community? >> i think it has already. >> reporter: generations have leaned on the city for hope and new beginnings. now heartbreak in the new year is bringing them even closer together. >> we don't want this to be sort of what monterey park is known for. it's so much more than a city that's been marked by a mass shooting. >> kathy park, nbc news, monterey, california. we'll turn now to iowa and yet another deadly shooting. this time at a des moines charter school. tonight two students are dead and a staff member wounded. maggie vespa has been following this for us. maggie, police say

this was targeted. >> reporter: lester, targeted. and police say they have three suspects in custody in this shooting. it happened at 1:00 p.m. at a des moines charter high school for at risk students. police responded finding three people shot. officers performed cpr, but two students died at the hospital. the third victim is a staff member in serious condition. police later got a tip about a car and found it two miles from the school. they say three people were inside. one ran, and police used a k-9 to track that person down. investigators not naming their suspects or the victims at this time. and tonight iowa's governor kim reynolds saying she is shocked and saddened by this shooting. reporters are looking at the most serious charges of murder. lester? maggie vespa tonight. thanks very much. let's turn to the investigation of president biden's handling of classified material and the discovery of more secret documents in his delaware home as he faces new criticism from democrats. kelly o'donnell now with the latest. >> reporter: the president returned to the white house today

facing a wider, more complicated bind with more classified records found at his delaware home. this time during an unprecedented fbi search of a sitting president's residence. the white house said agents were invited with no search warrant issued. some of the additional six items discovered date back to his senate years, according to the president's personal lawyer, suggesting those were not part of packing up his vice presidential office. today i pressed a white house counsel spokesman. are there any other searches at any other locations? >> look, we're not going to get ahead of the department of justice and their investigatory process. this is a responsible way to make sure they're able to conduct an investigation independent and thoroughly without undue influence from the outside. >> reporter: the white house refuses to answer key questions, including how many classified documents were found. >> this smells to high heaven with the constant drip, drip,

drip of finding more of these after he tells us one week after another there is no there there. >> reporter: government secrets have been found on five dates. since november at the biden home, garage and an office in d.c. the white house stresses its full cooperation with the doj. while some top democrats say damage has been done. >> let's be honest about it, when that information is found, it diminishes the stature of any person who is in possession of it because it is not supposed to happen. >> reporter: today the white house counsel's office responded to house republicans who requested answers on the documents matter saying officials here will try to accommodate, quote, legitimate oversight interests. lester? >> kelly o'donnell tonight, thank you. this evening a former top fbi counter intelligence official has been indicted for allegedly helping a sanctioned russian billionaire and for allegedly taking hundreds of thousands in secret payments. ken dilanian is following this.

what do we know? >> reporter: charles mcgonigal was the head of the new york fbi counter intelligence division, which meant his job was to protect the united states from improper foreign influence. he is now charged with profiting from foreign influence both while he worked as a top fbi official and after he left. while at the fbi, he secretly took $225,000 from a former albanian intelligence officer in what they call an illegal scheme to hide a conflict of interest. after he retired, mcgonigal went to work for oleg deripaska a sanctioned russian oligarch with close ties to vladimir putin. mcgonigal was arrested saturday at jfk airport in new york. he pleaded not guilty today and his lawyers say he intends to fight the charges. lester? >> ken delanian, thank you. new convictions tonight for some of those that took part in the january 6th attack on the capitol. richard barnett, the
