A Pennsylvania man blew up his own home on the day of his daughter’s wedding in what was being investigated as a suicide, authorities said.

The homeowner was found dead in the wreckage Saturday after an explosion and fire destroyed his property in Edgewood, 7 miles east of Pittsburgh, news station WTAE reported.

Neighbors said they spotted the man — whose identity wasn’t released — on the sidewalk before the home went up in flames.

“The whole house was on fire,” neighbor Rochelle Levine told WTAE. “The whole house was one big flame. It just exploded within a couple minutes.”

Edgewood Police Chief Robert Payne said the department is investigating the explosion as a suspicious incident.

“It looks like he disconnected the gas line in the basement of the house and of course, it wouldn’t take much of a spark to explode the house,” Payne told the news outlet.

Officials said suicide notes were discovered in the homeowner’s vehicle.

Nicole Antolovich, a neighbor, said the explosion came the same day as the wedding of the man’s daughter, WTAE reported.

“I’ve known them my whole life,” Antolovich told the news station. “Their daughter was getting married today and they were supposed to be at a wedding.”
