NASHVILLE, Tenn. (AP) — The man who snatched an AR-15 rifle from a gunman at a busy Tennessee restaurant says his was a "selfish" act of self-preservation and he doesn't consider himself a hero. Never mind that he is being credited with saving several other lives.

"When I grabbed the barrel of the weapon it was hot, but I didn't care. It was life or death," said James Shaw Jr., a 29-year-old Nashville resident who found himself wrestling with the suspect after four people had already been fatally shot at a Waffle House bustling with wee hour patrons early Sunday in Nashville.

Shaw joined law enforcement officials and Nashville's mayor at a news conference Sunday, some 12 hours after the shooting, his right hand bandaged. There he was singled out by Waffle House CEO Walter Ehmer, who was present and thanked Shaw for his bravery.

"You don't get to meet too many heroes in life," Ehmer said before addressing Shaw, who dabbed at tears in his eyes. "We are forever in your debt."

Shaw said that after going to a nightclub he had decided to stop with a friend early Sunday at a Waffle House. But the first one he visited was too crowded with overnight patrons, so he ended up going to another in Nashville.

As he entered the Waffle House, he was just two minutes ahead of the gunman, seating himself at a counter.

Suddenly he heard a loud noise, thinking at first that freshly washed plates had crashed from a stack in the restaurant. Then, he said, he saw restaurant workers running and turned and saw a body near the front door as the gunman burst in.

It was then that he realized he was hearing gunshots.

"I looked back and I saw a person lying on the ground right at the entrance of the door, then I jumped and slid ... I went behind a push door — a swivel door," Shaw said. "He shot through that door; I'm pretty sure he grazed my arm. At that time I made up my mind ... that he was going to have to work to kill me. When the gun jammed or whatever happened, I hit him with the swivel door."

Shaw said it was then that they began wrestling, ignoring his own pain as he grabbed the hot barrel of the AR-15 weapon. On Sunday afternoon, his right hand was bandaged from the encounter.

"He was kind of cussing while we were wrestling around. When I finally got the gun he was cussing like I was in the wrong," he said. "It wasn't any kind of talking between us; I just knew I just had to get that away from him."

Of the gun, he added: "I grabbed it from him and threw it over the countertop and I just took him with me out the entrance."

Shaw said after getting the man out of the Waffle House, he then ran one way and saw the suspect, naked save for a jacket, going another way.

Shaw said he had an apparent bullet graze on one elbow and fell and hit his knee as he escaped, landing in the hospital for a time early Sunday.

"I didn't really fight that man to save everyone else. That may not be a popular thing," said Shaw, a Nashville native who went to college in Tennessee and now works as a wireless technician. "I took the gun so I could get myself out" of the situation.

He said he was glad others were saved.

When Shaw's father went to visit him in the hospital early Sunday before he was released, he had one piece of advice for his son: "Don't do that again."

"I take no pride in him charging a loaded gun," James Shaw Sr. said. "I do take pride in him helping save the lives of other people."

More than 80 Nashville police officers continued to search for the suspect, Travis Reinking early Monday, authorities said. Agents with the FBI, the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives and troopers with the Tennessee Highway Patrol were also assisting in the manhunt as disturbing reports about the wanted man's past behavior came to light.

He was also added to the Tennessee Bureau of Investigation's Top 10 Most Wanted list.

Reinking was nearly naked, wearing only a green jacket and brandishing an assault-style rifle when he opened fire in the parking lot and then stormed the restaurant, police say. In addition to the four people killed, four others were injured. Police credit a quick-thinking customer who wrestled the gun away from the suspect for preventing more loss of life.

Metropolitan Nashville Police Chief Steve Anderson said at a news conference that Reinking, 29, was last seen Sunday around a wooded area near an apartment complex where he lived. Authorities said Reinking could be armed and weren't ruling out that he had left the area. He was believed to be wearing only pants and no shirt or shoes.

Nashville Police Chief Steve Anderson said there was no clear motive, though Reinking may have "mental issues." He may still be armed, Anderson told a mid-afternoon news conference, because he was known to have owned a handgun that authorities have not recovered.

"He's on foot," Anderson said. "Unless he's been picked up by a car, he would be fairly close. We don't want to alarm people, but certainly, everybody should take precautions. It could be he's in an unoccupied house. We want everybody to be concerned. Neighbors should check on each other."

Reinking was arrested by agents with the U.S. Secret Service back in July after he crossed a restricted area near the White House, officials said. He was detained after refusing to leave, saying he wanted to meet President Donald Trump.

In May 2016, deputies from Tazewell County, Illinois, were called to a CVS parking lot. Reinking told officers that Taylor Swift was stalking him and hacking his phone, and that his family was also involved, according to a report released Sunday.

It is not clear why Reinking moved to Nashville and if it had anything to do with being near the pop/country superstar. Police say he was employed in construction for a while and there would have been enough work in the booming city for him.

The victims fatally shot in the parking have been identified as Taurean Sanderlin, 29, of Goodlettsville, and Joe Perez, 20, of Nashville.

Sanderlin was an employee at the restaurant.

Perez's mother posted a picture of her son on Facebook and asked for prayers, saying it was the hardest day of her life. "Me, my husband and sons are broken right now with this loss," Trisha Perez said in the post. "Our lives are shattered."

Reinking then went inside the restaurant and opened fire, police said.

One of the fatally wounded inside was DeEbony Groves, a 21-year student at Nashville's Belmont University.

Groves was remembered as an exceptional student who made the Dean's list and a tenacious basketball player.

Akilah Dasilva was also killed inside the restaurant. The 23-year-old from Antioch was a rap artist and music video producer who had such skills behind the camera.
