NASHVILLE, Tenn. (AP) — A sheriff in Illinois says Travis Reinking’s state firearms card was revoked last year by state police, but his guns were given to his father with the promise that they wouldn’t be shared with his son.

Police in Tennessee are searching for the 29-year-old Reinking, saying he’s suspected of fatally shooting four people at a Nashville restaurant early Sunday. The Metro Nashville Police Department says arrest warrants charging Reinking with murder have been issued. Police say Reinking was from Morton, Illinois, but moved to Nashville in 2017.

Sheriff Robert Huston in Tazewell County, Illinois, says his department has “no information” on how Reinking got the weapons again. Huston says Reinking’s father has a valid firearm ownership card, and his officers didn’t believe they had any authority to seize the weapons. He says the father agreed to “keep the weapons secure and out of the possession of Travis.”

Phone calls to an Illinois phone number for Jeffrey Reinking, the father of the suspect, went unanswered.
