Clark County prosecutors said Wednesday they did not have enough evidence to file terrorism-related charges against a woman arrested with a stockpile of weapons at a Henderson casino.
Allison Howlett, 36, was arraigned July 1 on 35 felony counts, including assault constituting domestic violence with use of a deadly weapon, grand larceny of a motor vehicle, 21 counts of larceny of a firearm, eight possession of a machine gun or silencer and four counts of possession of a short-barreled rifle or shotgun.
Police announced Howlett’s arrest at a June 30 news conference, saying she was suspected of making a threat related to an act of terrorism and several other offenses after officers took her into custody June 27 in the parking garage at Sunset Station. Howlett’s arrest report states authorities recovered 24 guns, as well as hundreds of rounds of ammunition, from the sedan Howlett was in.
Clark County District Attorney Steve Wolfson said Wednesday in an emailed statement prosecutors found sufficient evidence to pursue the remaining felony charges but not a terrorism-related offense.
”In the case in question, a determination was made that there was insufficient evidence to support a charge involving a terroristic threat,” Wolfson said in the statement. “However, we did determine there was sufficient evidence to file all of the many other felony charges.”
Police detailed alleged threats at briefing
Howlett was taken into custody after her wife called 911 and said that Howlett had stolen her car, which contained several firearms. The caller said Howlett intended to commit “suicide by cop” or carry out a mass shooting, Henderson Police Chief Reggie Rader said during a joint briefing with the Metropolitan Police Department and FBI.
Howlett denied wrongdoing, according to her arrest report, and told investigators that users of the online communication platform Discord were trying to get her into trouble by making up threats that she would commit a mass shooting. Police also recovered 26 additional firearms from Howlett’s home in Henderson.
Howlett’s wife told investigators that Howlett left their home after an argument over money, Howlett’s arrest report said.
The spouse told police that, from January 2024 to January 2025, Howlett made “numerous threats to commit mass shootings when she would get angry,” according to Howlett’s arrest report.
At the June 30 briefing, Metro Assistant Sheriff Dori Koren said the FBI’s Joint Terrorism Task Force identified “several threats” made by Howlett.
Police said Howlett’s wife also showed investigators a 38-minute video from January 2024, in which Howlett threatened to shoot up the Las Vegas Strip, according to Howlett’s arrest report. In that video, Howlett expressed she wanted cops to “shoot me dead” and there would be a mass shooting if authorities didn’t arrest her.
Howlett preliminary hearing scheduled July 15
Howlett remained in custody at the Clark County Detention Center as of Wednesday, online jail records showed. Her bail is set at $500,000, and she is due back in court next week.
A public defender representing Howlett could not be reached for comment.
During the June 30 briefing, police referred to Howlett as both male and female. Howlett’s arrest report identified her as transgender.
A Metro spokesperson has since said Howlett was born male and lives as a woman but is listed male on jail records because she had not fully transitioned.
