DEWITT, N.Y. — Fire investigators are trying to determine what caused a blaze at a suburban Syracuse business where five tractor-trailer trucks went up in flames.

Officials tell The Post-Standard of Syracuse (http://bit.ly/2to9yJh ) that the fire was reported around 4 a.m. Monday at Beam Mack Sales & Service in the town of DeWitt.

The blaze spread to five truck cabs, which weren’t attached to trailers. It took firefighters around an hour to douse the flames, which were fed by fuel in the trucks’ gas tanks.

No one was injured.

The case has been turned over to Onondaga County fire investigators.
