As an intensive manhunt continued Monday for a half-naked man suspected in the slayings of four people at a Waffle House restaurant, authorities shared reports of previous efforts to contain the gun-loving man with paranoid delusions.

More than 80 Nashville police officers continued to search for 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 joined the manhunt.

He was also added to the Tennessee Bureau of Investigation鈥檚 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. Four people were killed and four others were injured before a quick-thinking customer wrestled the gun away, preventing more bloodshed.

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, wearing only pants and no shirt or shoes.

Anderson said it鈥檚 not clear why Reinking opened fire on restaurant patrons with an assault weapon, though he may have 鈥渕ental issues.鈥�

He may still be armed, Anderson said, because he was known to have owned a handgun authorities have not recovered.

鈥淗e鈥檚 on foot,鈥� Anderson said. 鈥淯nless he鈥檚 been picked up by a car, he would be fairly close. We don鈥檛 want to alarm people, but certainly, everybody should take precautions. It could be he鈥檚 in an unoccupied house. We want everybody to be concerned. Neighbors should check on each other.鈥�

Nashville public schools will go into 鈥渓ock-out鈥� mode if Reinking isn鈥檛 found in time for class Monday, officials said. That means students will be free to move about the building, but no guests or visitors will be allowed to enter.

As the search continued, authorities in Illinois shared past reports suggesting multiple red flags about a disturbed young man with paranoid delusions who liked firearms.

MNPD officers, to include SWAT, have continued the search for Travis Reinking in the Antioch area overnight. There have been no credible sightings. The search will continue. All schools in the area have been cleared by officers. He was last seen Sun morn behind his apt complex.

In May 2016, Reinking told deputies from Tazewell County, Illinois, that music superstar Taylor Swift was stalking him and hacking his phone, and that his family was also involved, according to a report released Sunday.

Another sheriff鈥檚 report said Reinking barged into a community pool in Tremont, Illinois, last June, and jumped into the water wearing a pink woman鈥檚 coat over his underwear. Investigators believed he had an AR-15 rifle in his car trunk, but it was never displayed. No charges were filed.

Last July, Reinking was arrested by the U.S. Secret Service after he crossed into a restricted area near the White House and refused to leave, saying he wanted to meet President Donald Trump. Reinking was not armed at the time, but at the FBI鈥檚 request, state police in Illinois revoked his state firearms card and seized four guns from him, authorities said.

The AR-15 used in the shootings was among the firearms seized.

Then, in August, Reinking told police he wanted to file a report about 20 to 30 people tapping into his computer and phone and people 鈥渂arking like dogs鈥� outside his residence, according to a report.

Reinking agreed to go to a local hospital for an evaluation after repeatedly resisting the request, the report said.

鈥淭here鈥檚 certainly evidence that there鈥檚 some sort of mental health issues involved,鈥� Tazwell County Sheriff Robert Huston said. But he said deputies returned the guns to Reinking鈥檚 father on the promise that he would 鈥渒eep the weapons secure and out of the possession of Travis.鈥�

Nashville Police spokesman Don Aaron said that Reinking鈥檚 father 鈥渉as now acknowledged giving them back鈥� to his son.

After the shooting, police recovered three of the four guns originally taken from Reinking, officials said. They believe he still has at least one handgun.

Phone calls to a number listed for the father, Jeffrey Reinking, went unanswered.

It is not clear why Reinking moved recently from Morton, Illinois, to Nashville and if it had anything to do with being near Swift. Police say he was employed in construction for a while, and there would have been enough work in the booming city for him.

Police say Reinking drove into the Waffle House parking lot in his gold Chevy Silverado pickup early Sunday and sat there for about four minutes before opening fire outside the restaurant.

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鈥檚 mother posted a picture of her son on Facebook and asked for prayers, saying it was the hardest day of her life. 鈥淢e, my husband and sons are broken right now with this loss,鈥� Trisha Perez said in the post. 鈥淥ur lives are shattered.鈥�

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鈥檚 Belmont University. She was remembered as an exceptional student who made the Dean鈥檚 list, and a tenacious basketball player.

鈥淪he was a brilliant young lady, very, very intelligent and a very hard worker,鈥� Gallatin High School basketball coach Kim Kendrick told The Tennessean.

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 that he was a favourite among many of Music City鈥檚 independent musicians and recording labels, The Tennessean reported.

鈥淢usic is my life and I will never stop until I achieve my dreams,鈥� Dasilva said on his Twitter account.

Dasilva鈥檚 mother told CBS 亚洲天堂 that her son was a student at Middle Tennessee State University and aspired to be a music engineer.

He was at the restaurant with his girlfriend, 21-year-old Tia Waggoner, the paper reported. Waggoner was wounded and is being treated at Vanderbilt University Medical Center. Dasilva鈥檚 family said she underwent surgery and doctors were trying to save her leg.

Police say Sharita Henderson, 24, of Antioch, was wounded and is being treated at VUMC.

Also wounded was James Shaw Jr., a 29-year-old restaurant patron who burned his hand grabbing the hot muzzle of the assault weapon as he wrestled the gun away. A Nashville native who works as a wireless technician for AT&T, Shaw said he was no hero 鈥� despite being hailed as one by Nashville Mayor David Briley.

Shaw said he pounced on the suspect out of self-preservation, after making up his mind that 鈥渉e was going to have to work to kill me.鈥�
