Last July, the U.S. Secret Service arrested Travis Reinking, the 29-year-old suspect in Sunday's murder of four people at a Waffle House in Nashville, for being in a restricted area near the White House and refusing to leave, saying he wanted to meet President Trump. In the fall, state police in Illinois revoked Reinking's firearm license at the request of the FBI, and police took away four of his guns, including the AR-15 used in the Nashville shooting, authorities said. Deputies returned the weapons to Reinking's father, Jeffrey Reinking, on the promise that he would "keep the weapons secure and out of the possession of Travis," Tazewell County, Illinois, Sheriff Robert Huston said Sunday, adding that based on past encounters with the younger Reinking, "there's certainly evidence that there's some sort of mental health issues involved." Nashville Police spokesman Don Aaron said that Jeffrey Reinking "has now acknowledged giving them back to his son."
