Mark Constantino, who starred on Ghost Adventures with his wife Debra Constantino, reportedly shot dead his spouse and costar before turning the gun on himself Tuesday. Another man was also killed.

‘Ghost Adventures’ Murder-Suicide

The Constantinos, after years of domestic violence incidents, had been living separately at the time of the deaths. Debra has been living with two roommates, one of whom was 55-year-old James Andersonaccording to Fox News. When the other roommate arrived home and found Anderson dead and Debra missing, she phoned authorities.

Authorities were eventually led to the home of the Constantino’s 23-year-old daughter in Sparks, Nev. Upon arrival at the home, police heard gunshots. Mark warned them that it was a “hostage situation,” and told police to “give me 15 minutes to gather my thoughts or I’ll kill her,” reported the Reno Gazette Journal.

Negotiations proved futile. Eventually a SWAT team used explosives to blast their way through the front door of the apartment. Inside, they found both Mark and Debra dead in an apparent murder-suicide.

Mark and Debra, a husband and wife team of paranormal investigators, recurred together on the Travel Channel’s Ghost Adventures. On the show, which launched in 2008, the couple showed off their expertise in Electronic Voice Phenomenon.

Neither the Travel Channel nor Ghost Adventures has released a statement regarding the deaths of the Constantinos. Ghost Adventures is currently in its 11th season on the Travel Channel.
