In March, Debby was arrested and charged with domestic violence after a dispute with her husband.
The fiery redhead drunkenly slashed Mark's forearm during a heated argument over their finances in their kitchen, authorities said. Between 2008 and 2011, the couple appeared in several episodes of Ghost Adventures, where they helped the shows hosts "speak" to ghosts by way of their recordings.
Mark later told police that he did not report the attack because this is "everyday behavior" by his wife, sources said.
Six weeks before their death, Mark allegedly kidnapped and strangled Debra, according to the affiliate.
The couple were recurring cast members on the long-running "Ghost Adventures", and were considered experts in "Electronic Voice Phenomenon", also known as EVPs.
