A Las Vegas woman has been arrested and charged with murder after allegedly shooting her boyfriend dead while posing with a gun during an early morning photoshoot.

Police say 20-year-old Allysandra Blea was modeling with a firearm as her boyfriend, Mark Gaughan, 23, photographed her around 4:30 a.m. on August 23 when the weapon discharged, striking him in the neck. Gaughan collapsed on the sidewalk outside their home, about three miles south of North Las Vegas Airport, and was pronounced dead at the scene despite frantic life-saving efforts.

Blea was charged with Open Murder with a Deadly Weapon on August 26 and booked into the Clark County Detention Center.

Investigators recovered Polaroid photos from the scene showing Blea posing with a gun and another young woman holding a knife. The second woman told police she believed the firearm had been unloaded when it was handed to Blea but later noticed the magazine had been reinserted.

Blea insisted the shooting was accidental, claiming she had never taken a firearm safety course and thought the weapon was empty. However, detectives uncovered evidence of her disturbing obsession with guns.

According to the arrest report, a review of Blea’s social media revealed repeated references to stockpiling weapons and violent fantasies. In one message, she allegedly wrote: “I wish I could shoot people with real guns and get away with it,” while another exchange described plans to target the homeless: “We gotta shoot someone real… If it’s only one a night, the police will remain clueless.”

Police concluded that Blea had “knowledge and experience of firearms” and described her behavior as a “fascination with firearms.”

Blea made her first court appearance on September 2 before Judge Nancy Bernstein at the Las Vegas Township Justice Court, where she was formally charged with murder. Her preliminary hearing is set for October 2.
