The couple had been estranged for some time and it is reported their deaths were the result of a murder-suicide. A third, currently unidentified man was also killed.

Debby had been living separately from Mark and shared an apartment with two roommates, according to reports on KTVN. The police were called to the residence at approximately 8.00am on Wednesday morning after Debby’s third roommate returned home and discovered the unidentified male roommate dead.

Debby was missing from the apartment and had been taken hostage by Mark at a different residence, an apartment reportedly owned by one of the couple’s adult children.
