A New York man who blew up his home in an apparent suicide attempt walked out of the blaze unscathed — but now faces arson charges in the terrifying ordeal, cops and witnesses said.

Santo Cok, 73, was not injured in Thursday’s blast that destroyed his residence on Covington Road in North Buffalo and seriously damaged both neighboring homes. Cok, who was in the basement at the time, told a stunned neighbor when he walked out of the inferno that he lit a candle just before the explosion, WKBW reports.

The neighbor, Laurie Brown, said she spotted Cok in the burning home after she sprinted over to check on any possible victims from the blast.

“There was fire all around him,” she said. “The walls had blown apart and this older man is standing there, not a mark on him.”

Cok “walked right through” burning debris before Brown and others helped him across the street to a neighbor’s house, she said.

Investigators believe Cok lit the candle because he “intentionally wanted to blow the house up to commit suicide,” Buffalo police Capt. Jeff Rinaldo said.

Miraculously, no one was hurt. Cok was taken to a hospital for evaluation and now faces charges of arson, criminal mischief and reckless endangerment.

“It’s kind of a miracle that nobody else was injured,” Rinaldo told WKBW. “Our police officer did an amazing job getting in quickly [and] getting all the houses cleared out.”

James Kraws, who lives across the street from Cok, said he mostly kept to himself.

“He was kind of a recluse,” Kraws told the Buffalo News. “He would never come out of his house. He lived on the second floor and would never come down.”

Kraws said he was shocked by the size of the explosion.

“It was quite a blast,” he said. “When I went to the window, it was absolutely unbelievable. Flames were coming out of the first floor, second floor and the roof that fast. It was instantaneous.”
