LAS VEGAS (FOX5) — Authorities from multiple agencies announced the recent arrest of a suspect in connection with a terrorism-related investigation.
Police said Allison Howlett, 36, faces multiple felony charges, including allegedly making threats related to an act of terrorism.
Henderson Police said dispatchers received a 911 call around 9:38 a.m. Saturday, June 27 about a domestic dispute.
The caller reported Howlett stole her car and that it was loaded with firearms, and said the suspect made threats about “suicide by cop” and a possible mass shooting.

Officers used vehicle tracking information and, with assistance from Sunset Station Casino security, located the car in the casino’s parking garage around 11:17 a.m.
Police said Howlett initially refused commands to get out while music played loudly inside the vehicle. Officers blocked the car in to prevent Howlett from leaving, then took the suspect into custody after rolling down the window when reaching for water.
During the struggle, Howlett was tased once, police add.
LVMPD’s counterterrorism detectives and the FBI Joint Terrorism Task Force responded after authorities learned more about the reported threats and the number of weapons involved.

Police said a search of the vehicle recovered 22 firearms and hundreds of rounds of ammunition, and a search of the suspect’s Henderson residence recovered 30 more firearms, along with suppressors and thousands of rounds of ammunition.
Howlett was booked on charges that include assault with a deadly weapon (domestic violence), making a threat related to an act of terrorism, grand larceny of a vehicle and a firearm, resisting a public officer with a firearm, and multiple weapons-related counts involving short-barreled rifles, machine guns, and silencers.
Howlett is due in court on Wednesday.
