According to authorities, Mark was living with his parents when the Stoneham police received a 911 call last January 23rd, 2010, reporting an altercation between Mark and a female. His father Daniel came home to calm his son down, but after the police left, Mark reportedly consumed large amounts of hard alcohol
and began to repeatedly argue with his parents, who wouldn't allow him to use the telephone to call the female. After getting in a heated argument
with Daniel, the situation escalated into a violent physical altercation when according to authorities, Mark "pushed, grabbed and shoved" the 70-year-old victim. He then reportedly forcibly grabbed his father around the neck, causing him to fall to the kitchen floor onto his back, unconscious.
