A 52-year-old Lawrence man died after firefighters found him inside his burning garage early Saturday morning, Lawrence-Douglas County Fire Medical Chief Mark Bradford said Monday.

James Beal Clark died at Kansas University Hospital after being taken by air ambulance from his home at 1124 Randall Road, Bradford said. Firefighters had responded to a report of a garage fire at the home just after 1:30 a.m. Saturday.

Firefighters made it to the scene “within five minutes” of the report, Bradford said, and found the garage in flames. Inside, firefighters discovered Clark still alive and immediately requested an air ambulance, Bradford said.

He was taken in critical condition to the KU Hospital’s burn center, where he “succumbed to his injuries,” Bradford said.

Bradford said that the case remains under investigation and that he did not know whether foul play was suspected.

The fire was contained to the garage area, never spreading to the attached home, Bradford said. Clark was the only person at the residence when first-responders arrived.

Fire investigators were working to determine the fire’s cause on Monday, Bradford said. Damages are estimated at $50,000, but Bradford said that amount could change pending further investigation.
