The couple has had a long history with domestic violence, generally coming from Debby, according to the New York Post. In fact, Mark and Debby have been involved in 10 separate domestic abuse incidents in the past three years alone, “with Debra acting as the primary aggressor in a majority of the incidents,” according to a police source.
Debby’s first arrest was in 2012, resulting from a domestic battery charge after she drunkenly fought both Mark and their daughter. Unfortunately, that was just the beginning. In March, 2015, Debby was again in trouble for domestic battery when she used a grapefruit knife on Mark, slashing his forearms in a heated debated about their finances, according to authorities.
And in August, 2015, Debra filed for divorce with claims that Mark, along with their 23-year-old daughter, had pulled her from her car before strangling her.
The couple’s final altercation was the most violent yet, with police tracking Debby and Mark’s cell phones to their daughter’s apartment. Authorities attempted to negotiate with Mark for two hours but were ultimately unable to convince him not to follow through with killing he and Debby.
