A 70-year-old Glenarden man was killed in a fiery crash on Martin Luther King Jr. Highway in the Landover area Monday afternoon, and a veteran Prince George’s County police officer was burned and cut trying to pull him from the wreckage, authorities said.

The incident occurred about 12:40 p.m., as the man was headed west on Martin Luther King Jr. Highway near Whitfield Chapel Road, police said. The man’s Mercury Mountaineer hit a guard rail and flipped onto its driver’s side, eventually coming to a stop on a Beltway overpass, police said.

Police said the SUV caught fire with the driver – 70-year-old Rodwell McNeill, Jr. – trapped inside, and three Prince George’s County police officers tried to pull him out. An 21-year veteran with the department’s Intelligence Unit, police said, suffered burns to his hands and face and was taken to the hospital for treatment.  His injuries were considered serious but not life threatening, fire officials said.

Preliminarily, investigators believe speed was a factor in causing the crash, police said.
