Police moved in outside a Las Vegas-area casino after a spouse warned that an armed transgender-identifying man had taken a weapon-filled vehicle and previously threatened mass violence.
The warning brought police to Sunset Station Casino in Henderson, where 36-year-old “Allison” Howlett was arrested Saturday after the spouse reported the alleged threat “to commit suicide by cop and carry out a mass shooting.”
The arrest charges included “threats related to an act of terrorism,” Andrew Walsh of the Las Vegas Metro Police Department said Tuesday.
Other counts listed against Howlett include gun theft, car theft, resisting an officer with a gun, and making a threat of terrorism or false information about an act of terrorism.
The case briefing included audio that police attributed to Howlett and presented as a mass-violence threat.
“I swear to God, if the FBI doesn’t come f***ing arrest me, there’s gonna be a f***ing mass shooting,” the person said in the recording. “There’s one day you’re gonna be pissing me the f*** off, and it’s gonna be the last f***ing straw.”
A police report obtained by the Las Vegas Review Journal described Howlett rejecting the allegations that there was any intent to hurt people or any prior mass-shooting threat.

“Allison denied wanting to hurt anyone and denied making any prior threats to commit a mass shooting,” the report said. “Allison stated that everyone is out to get her and are setting her up.”
Henderson Police Department Chief Reggie Rader placed Howlett back at Sunset Station Casino on June 27, describing a standoff-like scene with loud music coming from the vehicle and Howlett refusing to exit.
“The quick-thinking officers developed a plan to take her into custody as an opportunity arose when she reached for the water. Officers used that moment to gain control over her hands and remove her from the vehicle,” Rader said.
The video shown at the briefing captured officers around the vehicle before Howlett was removed.
According to Rader, officers later learned Howlett was seated on a handgun and could reach a fully automatic machine gun in the back seat.
The car itself yielded 22 firearms and hundreds of rounds of ammunition, including rifles and multiple handguns.
Howlett’s wife Julie, a firearms dealer, told Fox 5 that all of the weapons recovered from the car belonged to her.
She also said that the pair had gotten into an argument about Allison charging up Julie’s credit card, which escalated into Allison shooting at Julie, who managed to wrestle away the weapon.
Allison took off in Julie’s car, which was loaded with weapons she planned to transport to another dealer out of state.
Investigators later searched Howlett’s residence and recovered 30 additional firearms and thousands more rounds of ammunition.
Howlett’s next listed court date was a July 15 preliminary hearing, with bail set at $500,000.
In Texas, an alleged threat against a Lubbock Pride parade led to the arrest of a United States Postal Service employee, the FBI announced Monday.
Authorities identified the suspect as Michael Thompson of Clovis, New Mexico, and tied the case to threatening social media posts.
FBI Director Kash Patel framed the arrest as a law-enforcement success.
This weekend’s arrest out of Lubbock, Texas, is the best of this FBI and our law enforcement partners in action—yet again stopping a potentially deadly attack thanks to brilliant execution from our teams and partners.

“This weekend’s arrest out of Lubbock, Texas, is the best of this FBI and our law enforcement partners in action—yet again stopping a potentially deadly attack thanks to brilliant execution from our teams and partners,” Patel said.
“Our agents, intel teams, and state and local partners out of Texas acted decisively and stopped him before he could act.”
“More lives saved thanks to good cops being cops,” Patel added.
Thompson later acknowledged creating the posts and removing them, authorities said.
Thompson identified himself as a USPS employee, authorities said.
At Thompson’s residence, authorities recovered four firearms. The FBI tied the firearm charge to a prior felony domestic violence conviction that legally bars Thompson from gun possession.
The charges against Thompson include transmitting threatening interstate communications and being a felon in possession of a firearm.
The final case had already turned deadly at a Northern California library, where authorities later pointed to an alleged Columbine-style motive.
KCRA-TV reported that police placed the shooting at the Butte County Library in Chico, about an hour and a half north of Sacramento; KHSL-TV also reported on the library shooting.
The first emergency call came from the library at 5:12 p.m., KHSL reported.
According to the police chief cited by KHSL, the call captured the sounds of shots and screams from inside.
KHSL reported that officers entered from the front as the suspect tried to escape through the back, where he was tackled.
Video from station viewer Jeannie Lee Schroeder showed police holding the suspect on the ground.
Police identified the suspect as Bradley Scott Sayer, an 18-year-old Chico resident, and the Chico Police Department told KHSL he was booked into the Butte County Jail on two open counts of murder.
The shooting killed two adults, KHSL reported, and sent a juvenile to the hospital with non-life-threatening injuries.
The Federal Bureau of Investigation and the Butte County Sheriff’s Office are assisting Chico police as investigators review evidence and continue interviews, KHSL reported.
Investigators have not identified any additional suspect.
A Tuesday morning police news release said investigators had found no prior relationship or connection between Sayer and the victims who were inside the library.
KHSL cited police in reporting that Sayer’s motivation appeared to be “founded in a desire to commit a Columbine High School massacre-type shooting.”
KHSL also reported that a YouTube video pointed to Sayer graduating from Chico High School in June.
