Mark Constantino, the “Ghost Adventures” star, killed his co-star wife, her roommate and himself after years of physical abuse from his spouse, Nevada authorities say.

The Reno Gazette-Journal reported Friday that Janice Oberding met the Constantinos while teaching a class on ghost hunting and spirituality at the Truckee Meadows Community College in 2002. And that Mark Constantino arrived at a class with his daughter and asked to record the lecture for his wife.
Oberding told the paper she introduced the couple to Zak Bagans of the Travel Channel’s “Ghost Adventures.”
“We drifted apart and our friendship ended,” Oberding was quoted as saying. “But I know at one point she loved him very, very much and he loved her. …I never saw any physical violence. I don’t know what happened.”
