Mark and Debby Constantino from the popular Travel Channel show Ghost Adventures are dead in an apparent murder-suicide near Reno, Nevada. It all started Tuesday morning when a woman found her male roommate dead in her home.

Debby Constantino was also living there, but the woman reported that she was missing. So police tracked down Debby's cell phone and found her at her daughter's apartment. Mark was there too.

Upon arriving at the apartment, officers knocked on the door and heard a male voice. They tried negotiating with him but he just kept yelling at the police to leave.

The suspect told police "give me 15 minutes to gather my thoughts or I'll kill her." They then heard several shots fired.

Eventually, police used explosives to open the door only to find the couple dead in the apartment. They did not say how they were killed or what kind of gun was used.

Police said the couple had a long history of domestic violence. 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 were actually involved in several television programs about ghost hunting, including Ghost Adventures.
