TORONTO – Investigators continued their search for clues Wednesday into a Toronto home explosion in the city’s east-end that claimed the life of a 57-year-old man.

Wayne Romaine from the Ontario Fire Marshal’s office told reporters that they will be sifting through the wreckage, clear the debris, and try to pinpoint the exact location and source of the explosion.

“We’re going to go after the garage, the debris there, work along the south side,” said Romaine.

The explosion happened on Monday around 4 p.m. at a home located on Brimley Road in Scarborough.

Authorities say the body of the victim, identified as Paul Zigomanis, was found at the rear of the house.

Romaine said Tuesday the blast was gas related but the exact type of fuel remains unknown.

Neighbour Winnie Woo was the only other person injured in the explosion, her hand cut by glass.

“The lamp from the ceiling dropped and all the glass flying,” said Woo. “I thought it was the end of the world.”

Woo didn’t know Paul Zigomanis, but knew his parents John and Mary who owned the house. Mary died in March 2013, and John in Dec. 2014.

Global News has found that Zigomanis was due in court last Friday for assault causing bodily harm and uttering threats. Sources said the incident was a family dispute and the alleged victims are his two sisters.

Zigomanis failed to show up for court Friday, and an arrest warrant was issued. Three days later, the house blew up.

Four intact containers of acetylene, a gas used by welders, were found in the rubble of the home’s garage. Investigators said just one of those containers could blow up a house.

Work will begin Thursday on clearing debris, then at investigating the home’s gas delivery system and appliances for clues.
