Horror after male model asked gun-toting 19-year-old granddaughter of rumored serial killer to pose for photos

A Las Vegas woman with a ‘firearm fascination’ admitted to killing her male model friend during a photoshoot.

Allysandra Blea, who was 19 at the time, confessed to shooting Mark Santiago Gaughan, 23, as he snapped her pictures in August.

Blea pleaded guilty to first-degree kidnapping and involuntary manslaughter on Tuesday, KSNV reported.

In exchange, the prosecution will recommend a sentence of five years to life in prison for the kidnapping charge to run concurrently with the manslaughter charge, which has a maximum 10-year sentence, at her July 28 sentencing hearing.

‘I think from the defense perspective, we have tried to explain that the significant amount of alcohol and marijuana in a 19-year-old girl is what led to this horrible accident,’ Chief Deputy Public Defender Robert O’Brien told the Las Vegas Review-Journal.

On the day of the shooting, Blea, now 20, who has a bullseye tattoo on her chest, and another woman asked Gaughan to take pictures of them in a weapon-filled Polaroid photoshoot, police said.

When the two women were posing with a gun, Blea discharged the weapon and the bullet hit Gaughan in the neck. He died shortly after.

Authorities were called to the scene to respond to an ‘accidental shooting.’ They later retrieved photos of the women posing with knives and guns, KLAS reported.

One depicted Blea ‘lying back [on the other woman], holding a black firearm that was pointed at her mouth with her finger on the trigger,’ police said. The other woman was said to have been holding a blade.

Witnesses told police that Gaughan had brought the gun to a gathering before the fatal incident. They said he believed the chamber was empty.

lea and others admitted they had been drinking before Gaughan was killed.

However, detectives noted that Blea ‘was adamant that she did not intentionally kill Mark.’

‘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,’ police said.

But when police reviewed Blea’s social media accounts, they reportedly made a chilling discovery.

They said she seemingly had ‘a fascination with firearms’ and often spoke of wanting to shoot people.

When police confronted her about the posts, Blea claimed they were jokes.

‘She stated that they were a joke,’ a detective testified. ‘And she stated that her grandfather was actually a serial killer who was previously convicted in New Mexico.’

Blea’s paternal grandfather is Joseph Blea, who has been identified as a suspect in the infamous West Mesa murders.

In 2009, the remains of 11 women and an unborn child were found in a mass grave in Albuquerque’s West Mesa in New Mexico.

Although the crimes remain unsolved, Blea, who is a convicted rapist and is behind bars serving a 90-year prison sentence, has been identified as a suspect in the case. He has denied any involvement.

Gaughan was a model signed to the Las Vegas-based TNG Agency, according to his and the agency’s social media accounts.

TNG Agency shared an Instagram post confirming his untimely death in August.

‘A standout in the crowd. One of a kind. I will never forget him. I wish peace and strength to his mother, Caroline, and their friends and family,’ TNG Agency Founder and CEO Noelle Haddad-McCann commented.

In his tear-jerking obituary, Gaughan’s family described him as ‘someone who has made our world a brighter, better place,’ quoting the poem A Life Well Lived.

The Daily Mail contacted the public defender’s office and the district attorney’s office for comment.
