A man faces felony assault charges for allegedly threatening his girlfriend with a sawed-off shotgun in front of her children.The suspect, Jared Thomas Gum, 20, waived his right to a preliminary hearing before General Sessions Judge Bill Locke and was bound to the grand jury on charges of aggravated assault, two counts of reckless endangerment and possession of a prohibited weapon. His bond was reduced to $15,000 but he was warned to stay away from the victim if he gets out of jail.The woman said Gum showed her a sawed-off shotgun while they were in her driveway on Chaple Drive, telling her “this is what I’m going to kill you with.”The victim said her 13-month-old child was already strapped in a car seat so she left the driveway and headed toward her grandmother’s house.She says he followed her and forced her off the road near North Hills Drive. She was able to get back on the road and called 911 as she continued to her grandmother’s house.
