GIBSONTON-- Hillsborough County Fire Investigators are trying to find the cause of a fire that left a man dead Monday night.

Fire crews received a call around 8:30 p.m. of a house on fire in the 11000 block of East Bay Rd in Gibsonton. Upon arrival, they found a double wide mobile home with heavy fire and smoke coming from the inside. Crews tried to put out the fire, but due to the amount of fire and heat coming from the home, crews had to perform a defensive attack from outside the home.

It took crews nearly an hour to get the fire under control.

Once the fire was out crews were performing a search of the home when they found a dead man inside.

The cause of the fire is under investigation, and the identity of the victim is not released at this time.
