LAS VEGAS (KLAS) – A 20-year-old woman who Las Vegas police say had a “fascination” with guns is accused of shooting and killing her boyfriend while posing for photos with a firearm last month.

Allysandra Blea, 20, faces a charge of open murder in the death of Mark Gaughan, 23.

On Saturday, Aug. 23, just before 5 a.m., the Las Vegas Metropolitan Police Department received a 911 call about an accidental shooting in the city’s northwest valley.

Responding officers learned Gaughan was taking photos of two women, including Blea, who was posing with a gun when the firearm discharged, striking Gaughan, documents said. Gaughan died from a gunshot wound shortly afterward.

Police located Polaroids from the photoshoot showing one woman holding “a knife in her hand” and Blea “lying back [on the other woman], holding a black firearm that was pointed at her mouth with her finger on the trigger,” according to a police report. Another photo showed Blea “holding the firearm in her left hand with her finger on the trigger.”

A witness described Gaughan as Blea’s boyfriend and said Gaughan brought a gun to a gathering earlier in the evening and believed the chamber was empty, according to the documents.

Other witnesses, including Blea, told police the group was drinking before she and the other woman decided to take the photos.

“She stated it was an accident and admitted she has never taken any firearm safety courses and believed the firearm didn’t have a bullet in the chamber,” Blea told detectives, according to documents. “She was adamant that she did not intentionally kill Mark.”

Police reviewed Blea’s social media accounts and determined “she had a fascination with firearms,” they said.

“In several conversations with various accounts, there was talk about her love of shooting guns, owning guns, building her arsenal and shooting people in the face,” detectives said. “There were several photographs of Allysandra holding various firearms (handguns, revolvers and rifles) in different poses to include the firearm pressed against her head, against stuffed animals’ heads and shooting bottles at an unknown location.”

Police also noted Blea “had a bullseye target tattooed on her chest.”

In one conversation, Blea reportedly commented, “I wish I could shoot people with real guns and get away with it.”

The Clark County coroner’s office ruled Gaughan’s death a homicide.

During her initial court appearance in August, Las Vegas Justice Court Judge Suzan Baucum denied setting bail.
