Pictured: Prominent Las Vegas attorney and his wife killed by her former father-in-law who then turned weapon on himself at child custody hearing in law office

A leading Las Vegas attorney was among the two people shot dead at a law office on Monday.

Dennis Prince and his wife, Ashley Prince, were killed inside the offices of Prince Law Group in Summerlin when another attorney opened fire during a deposition before turning the gun on himself.

Robert Eglet, Dennis Prince's former law partner, described him as 'one of the best trial lawyers in the state.'

'It's a real loss to the community,' Eglet told the Las Vegas Review Journal. 'It's awful. It's a loss to our profession.

'This is every family's nightmare, something like this happening. I'm still trying to put my arms around the fact that this actually happened.'

Gunshots broke out in the firm's fifth-floor offices around 10 a.m. Monday

Speaking to KTNV, sources confirmed the gunman's identity as another attorney, Joseph Houston, who fatally shot the couple before taking his own life.

Ashley Prince was Houston's former daughter-in-law, the same sources said.

Houston and the Princes were present for a deposition Monday in a custody case involving Ashley and Houston's son, Dylan.

Ashley and Dylan Houston have two young children together, and records show Dylan filed for divorce in 2021.

Dennis Prince was representing his wife in the case, sources said. 

Clark County Sheriff Kevin McMahill said the shooting occurred at around 10 am on the firm's offices on the fifth floor.

As bullets flew, hundreds of other occupants sheltered in place. Officials later passed through the building and safely evacuated them.

'As you can imagine we have a five or six-story building,' McMahill told KLAS.

'We have people that are hunkered down following active shooter protocols. We're going door by door and making sure everybody in there is okay and evacuating them.'

An area for family reunifications was established on the fifth floor of the Red Rock Resort, just down the street from the office.

According to a biography on the law firm's website, Prince was the founding member and lead trial counsel on all major cases.

He was recognized as the Nevada Trial Lawyer of the Year in 2016 by the Nevada Justice Association and had tried more than 100 cases to jury verdict at the time of his death. 

GGRM Law Firm, a personal injury attorney based in Winchester, released a statement after news broke of the couple's death.

'Our esteemed colleague, Dennis Prince, and his wife, Ashley, were senselessly taken from us in an act of violence that has left us in shock and mourning,' the statement read.

'Dennis was not just a pillar in the legal community; he was a mentor, a friend, and an advocate for justice whose influence reached far beyond the courtroom.

'Alongside him, Ashley was a source of unwavering kindness and compassion, touching the lives of those around her with genuine warmth and generosity.'
