The house explosion that killed a 76-year-old man in suburban Cook County last month was caused by a natural gas leak, according to a preliminary report by federal investigators.

Around 2:05 p.m. on June 12, the home in the 14000 block of Kenneth Court in Crestwood exploded.

When firefighters arrived after the explosion, they found the home engulfed in flames, according to Crestwood Fire Department Chief Jonathan Newton. 

While battling the fire, crews learned a man had been inside the home when it exploded.

Due to extensive debris, firefighters could not locate the victim and shifted the effort from a rescue to a recovery mission.

Fire officials also said the cause of the explosion was a gas leak.
