Homeless man arrested after setting another man on fire

A homeless man was arrested Saturday after setting fire to another man from the same homeless camp.

According to the Pinellas County Sheriff's Office, Harold Rosenbaum Jr., 44, got into an argument just after midnight with James Heffernan, 60, inside a tent in a wooded area about 600 feet southeast of Tampa Road and Eastlake Road in Oldsmar.

The argument between Rosenbaum and Heffernan became physical.

Rosenbaum was arrested and faces charges of attempted murder. Heffernan was transported to a local trauma center with severe burns on 75 percent of his body. He remains in critical condition. Mahoney was also transported to a hospital with non-life threatening burns from trying to extinguish the fire. Rosenbaum was uninjured.
