A man possibly robbing storage units at a Federal Way Public Storage facility died in a fire on Christmas morning, police say.

About 7:55 a.m. Dec. 25, Federal Way police, South King Fire and Rescue and Valley Regional Fire Authority personnel responded to a commercial fire at a Public Storage facility, 32615 Pacific Highway South, said Cmdr. Kurt Schwan of FWPD.

During the incident, the body of a man was found in one of the units damaged by the fire, Schwan said. The man died at the scene.

The King County Medical Examiner identified the man as 42-year-old Shane Fitch. His cause of death was determined to be asphyxia due to inhalation of smoke and ruled as accidential.

Preliminary investigation by police concludes the deceased man may have been burglarizing the storage units at the time of the fire and was unable to escape prior to being overcome by the smoke or fire, Schwan said.

Detectives from the Criminal Investigations Section have responded to assist with the investigation and process the scene for evidence.
