“It was a domestic dispute between father and son about cleaning things up and trying to be a responsible teenage figure in his life, which he had down pretty good,” Rick McNamara told WAFF. “It’s just a your typical teenager not wanting to do things to help. It escalated.”

Linda McNamara said she still loves her grandson Jeffrey, who is currently being held at the Madison County Jail on a combined $200,000 bond.
