PEKIN, Ill. — The father of a man accused of killing four people at a Tennessee Waffle House is facing a weapons charge in Illinois.

Jeffrey Reinking was charged in Tazewell County Circuit Court on Thursday with unlawful delivery of a firearm.

Travis Reinking has been held without bond since the April 22 attack in Nashville. Authorities say Reinking was wearing only a green jacket when he opened fire at the Waffle House with an assault-style rifle. Police credit a quick-thinking restaurant patron with wrestling the rifle away from the gunman and likely preventing more deaths.
