He was taking a smoke break outside when the shooting started.
"I was very lucky - where I usually sit, one woman was killed and another was shot", he told CNN. One of them - the fourth fatality - later died at Vanderbilt University Medical Center.
A USA congressman is calling for restricting access to some assault weapons in the wake of a shooting at a restaurant in Tennessee on Sunday that left four people dead.
Jennifer Wetzel, a spokeswoman for the medical center, said one wounded victim was in critical condition and another was in critical but stable condition.
The dead were identified as 29-year-old restaurant worker Taurean C. Sanderlin, and restaurant patrons Joe R. Perez, 20, Akilah Dasilva, 23, and Deebony Groves, 21.
Speaking at a press conference, Nashville Mayor David Briley, a Democrat, said these "weapons of war" needed to be removed from the nation's streets. "The fragility of life was brought home to us all by the death of four innocent Nashvillians".
Police praised a customer who prevented further bloodshed in the shooting.
Mr Cordero said 29-year-old James Shaw, Jr, who wrestled the gun from the suspect, saved lives.
A witness tells WKRN that he drove up to the Waffle House at the same time as the suspect and later saw Shaw get the gun from the suspect. At that point, the shots had stopped.
One diner who had hidden near the restrooms dashed out and pulled the rifle from the gunman when he paused to re-load and tossed it over the counter.More news: Here's How To Watch Beyonce's Full Second Coachella 2018 Performance

Shaw said he slid from his table and moved toward the door, which the gunman was trying to enter after apparently firing through the glass.
The man who wrestled the gun away from Reinking and prevented him from killing more people doesn't want to be called a hero. "He was nude and fled on foot".
Later Sunday morning, he apparently "clothed himself with a pair of trousers", Aaron said. The vehicle Reinking arrived in to the restaurant is registered to him, and his driver's license had a Morton, Illinois, address. He was believed to be wearing only trousers and no shirt or shoes.
"Nashville woke up to devastating news", Cooper wrote on Twitter.
Some reports since the shooting claimed that a few months before Sunday's incident at the Waffle House, Reinking was arrested by authorities and his guns seized outside the White House grounds on Pennsylvania Avenue on July 7, 2017.
Reinking was later questioned by the Federal Bureau of Investigation and Tazewell County, Illinois, authorities. Reinking is accused of shooting patrons and employees with an AR-15 rifle about 3:25 a.m. Sunday morning. Authorities said Reinking could be armed and weren't ruling out that he had left the area.
"He was allowed to do that after he assured deputies he would keep them secure and away from Travis", Tazewell County Sheriff Robert M. Huston said, referring to Reinking's father. Police said he then gave them back to his son.
Police have the AK-15 and another gun found during a search earlier Sunday.
The fourth victim died in hospital and two others were wounded. He said he was unsure if the man was reloading or his weapon had jammed. "So our officers are definitely on alert". He said there were also unknown people outside his house barking like dogs, and that he was being watched.
