LAS VEGAS (KTNV) — Newly released body-worn camera footage is shedding new light on Shane Tamura, the 27-year-old gunman who shot and killed four people in New York City last Monday.
Jhovani Carrillo walks us through some of the things we've learned.
Tamura, who was a Las Vegas resident, has had prior incidents with law enforcement before. Las Vegas Metropolitan Police released additional body camera footage and 911 calls from three separate events as part of their joint-investigation with New York authorities.
The footage shows LVMPD conducting a wellness check of Tamura's residence as well as a prior traffic stop. Another video shows a 2023 incident where Tamura was arrested at Red Rock Casino Resort on a trespassing charge.

First wellness check incident
On Sep. 12, 2022, Tamura's mother called police saying her son was threatening to kill himself and had a handgun stored in his backpack. She also told police he had sleeping pills for insomnia.
His mother was present but had stepped outside, saying she was "afraid to leave."
"[Shane] didn't say he made a plan. He just said he just can't take it anymore," Tamura's mother can be heard telling police.
She confirmed with police that Tamura was being treated by a doctor for depression and concussions. "He is being treated, he's under a doctor's care for depression, concussion like sports concussions, chronic migraines, and insomnia," she said.
According to documents, Tamura told officers he was having a hard time coping with family issues. He said he was taking medication but it didn't seem to be working. Police asked Tamura if he wanted his mother to hang onto his firearm, but he declined. At that time, police did not have authority to confiscate firearms per Nevada law. (This law changed in the Nevada 2025 Legislature.)
Documents show that Tamura was taken to a medical facility due to concerns of self-harm.
Red Rock casino arrest and trespass charge
On Sep. 27, 2023, security at Red Rock Casino Resort and Spa called police to assist them with removing Tamura from the property after he was asked to leave.
According to an arrest report, Tamura had been gambling at the casino when security asked to see his ID. He refused and was asked to leave. Instead of leaving immediately, he went to the cashier's cage to collect winnings where he was again asked to show identification. He refused again and the police were called.
"He's making a spectacle of himself and there's about 10 officers on him right now," a Red Rock security officer can be heard telling police.
Tamura himself also called 911 that night, saying Red Rock was refusing to pay him his winnings.
"I'm at the Red Rock Casino and the casino is refusing to pass me out. Can you call gaming and get them to Red Rock Casino?" Tamura said to the operator. "They stole my money. They stole like $6,000 from me and they're not cashing me out. They stole my money."
The arrest report states Tamura was obstructive towards an officer and placed in handcuffs. He was taken to a security holding area to be questioned by more officers. Eventually, Tamura was escorted outside to a patrol car where he was released from the handcuffs and told to leave as he had now been trespassed.
Instead of leaving immediately, bodycamera footage shows him pulling out his ID and asking police how he can cash out his winnings so he can "make rent." Police warned him to leave or he would be arrested. After refusing to leave, Tamura was arrested for trespassing after a verbal warning.
He was booked to the Clark County Detention Center.
Traffic stop incident
On May 30, 2024, police officers conducted a traffic stop involving Tamura at Flamingo Road and University Center Drive.
Bodycamera footage shows police telling Tamura he was being pulled over due to missing license plates on his vehicle. Tamura apologized and gave police his license and registration, but police found it to be invalid and his registration expired.
Police cited him and told him to park his car and Uber home.
Second wellness check incident
On Aug. 10, 2024, law enforcement received another 911 call from Tamura's mother claiming he was suicidal. She told authorities he was diagnosed with bipolar depression and anxiety.
When medical personnel and police responded to the scene, Tamura made statements about "not wanting to be here anymore" but stayed calm and cooperative. Despite cooperation, he told responders he did not want to go to a hospital.
Police asked Tamura if he had a concealed weapons permit and he said yes. He explained he wasn't feeling well and was loaded onto a stretcher.
According to documents, Tamura was placed on a mental health hold due to this incident. At this time, similar to the 2022 incident, law enforcement did not have authority to confiscate firearms for a mental health hold.
Search and seizure warrant
On July 30, 2025 — two days after Tamura shot and killed four people in Manhattan — Las Vegas police conducted a search warrant at his residence.
According to documents, police seized the following from his home:
- A bipod for a rifle
- A notebook with a "goodbye note"
- A vehicle title
- Multiple prescription bottles with paperwork (some empty)
- An empty Colt gun case
- 9mm ammunition
- One rifle cartridge
Prior to receiving these bodycam videos and 911 calls, we knew that Tamura had a documented history of mental health problems. In addition to the two involuntary psychiatric holds in 2022 and 2024, ESPN reported that he had sought mental health help for years regarding headaches he started experiencing while playing high school football in California.
A scribbled note on Tamura's body at the time of the NYC shooting suggested he suffered from chronic traumatic encephalopathy, or CTE, and held grievances against the National Football League — his alleged target for the shooting.

Channel 13 learned that Tamura legally purchased his firearm from a coworker at Horseshoe Las Vegas, and his mental health holds did not block him from holding a concealed weapons permit.
New York officials said "lax gun laws" were to blame for the attack. We spoke with Nevada Gov. Joe Lombardo who refuted those claims, saying the focus should be on mental health instead of weapons.
