The bodies of two children and an adult were found Monday in a car that was set on fire, authorities said.

The car was found ablaze in an industrial park area of Springfield shortly before 10 a.m., police Capt. Robert Cheetham said.

Dennis Leger, a spokesman for the fire department, said the bodies and inside of the car were burned beyond recognition. He said the children were "really, really young, maybe 2 or 3 years old."

"As firefighters extinguished the fire they noticed there was somebody in the fire," he said. "By taking a closer look, there appeared to be two smaller bodies in there."

The car, believed to be a Dodge or Chrysler sedan, was in a parking lot away from other vehicles at Harvey Industries.

The company, headquartered in Waltham, manufactures doors and window frames and operates a warehouse in Springfield. A company official said there would be no immediate comment.

The Springfield arson and bomb squads were investigating.
