A man who reportedly held a gun to his head and threatened suicide before pushing his grandmother down has been bound to the grand jury on assault and weapons possession charges.The man, Joshua H. Grissom, 27, was bound to the grand jury following a preliminary hearing before General Sessions Judge Bill Locke. The court decided to reduce his charge from felony assault to misdemeanor assault but let stand his charge of possession of a firearm by a convicted felon.Grissom’s father told sheriff’s deputy Brystol Davis he awoke to sounds of his son and a woman shouting.“He tried to calm him down,” the deputy revealed, noting Grissom refused to calm down. “He pulled a handgun from his back pocket and pointed it at his own head and said he would shoot himself if he (his father) didn’t leave.”Grissom’s father contacted his mother (the defendant’s grandmother) and asked her to intervene.
