Police say the gunman was naked except for a green jacket when he opened fire at about 3:25 a.m. (4:25 a.m. ET) in Antioch, part of the Nashville area in Tennessee.
The assailant later shed his green jacket, which police found two AR-15 magazines in the pocket. Reinking later put on a pair of black pants, with no shirt. He is still at large with two guns, a hunting style rifle and a handgun.
It appears Reinking targeted African Americans in the Waffle House. His last message on Facebook, allegedly, is from March 30, 2017, and mentions the Illuminati.
In July 2017, the U.S. Secret Service arrested Reinking for being in a "restricted area" near the White House, according to the Secret Service. After the arrest, his Illinois firearms authorization was revoked and local Illinois police seized four weapons.
"Among the weapons seized by those authorities was the AR-15 rifle used at the Waffle House today," said a Nashville police spokesman at a Sunday afternoon news conference.
Police believe Reinking's father received the weapons after their confiscation, and returned them to his son.
Reinking may still have two weapons as police continue their manhunt. Police believe those weapons are a hunting rifle and a handgun.
Reinking is a patronymic name, a type of surname that derived from the given name of the father of the original bearer. Reinking was derived from the Old Germanic personal name Raginhari, which is composed of the Old German elements ragin, which means counsel, and hard, which means hardy.

A rather infamous multiple killing occurred at a Waffle House that is east of Interstate 75 in Davie, Florida, about 10 miles southwest of Fort Lauderdale. One site says that due to these "Waffle House Murders," this location is now haunted.
