Mark and Debby Constantino, a couple featured in episodes of the Travel Channel’s paranormal investigation series Ghost Adventures, were found dead on Tuesday in an apparent murder-suicide, police say.

Asreported by KTVN News, the bodies were discovered after a woman called police when she returned home and found one roommate, an as-of-yet unidentified man, dead and her other roommate, Debby Constantino, missing.

Reno police continued their investigation Wednesday but released few new details about the chain of events that led to Tuesday’s deaths of Mark and Debby Constantino in the Sparks apartment several hours after the killing of another man in Reno, reports USA Today.

Officers said they heard a man yelling at police to leave. Officers began negotiating with the man, but eventually used explosives to blow the door open and found the couple dead inside.

“The subjects involved in this incident were not shot at or injured by gunfire from any law enforcement personnel,” Sparks police Lt. Rocky Triplett said in an email Wednesday to The Associated Press.

According to KRNV-TV, police said the couple had a long history of domestic violence, and Mark Constantino had allegedly kidnapped Debbie Constantino a few months ago.

Records indicate he was arrested in August and booked on suspicion of domestic battery by strangulation, first-degree kidnapping and first-degree domestic battery.

The Constantinos lectured at paranormal conferences around the country and maintained a website, www.spirit-speak.com.
