The driver of the gasoline tanker that
plunged from an overpass onto Interstate 95 in January apparently suffered a heart
attack or other sudden medical problem that caused him to lose control of his
truck, The Associated Press reported.

Police found no evidence of serious mechanical defects with the tanker, which had
passed an inspection one week before the fiery crash that claimed four lives
and shut down I-95 near Elkridge for seven hours Jan. 13.

experienced a sudden cardiac event or other type of medical emergency, thus

The report said that the autopsy of tanker driver Jackie M.
Frost, 64, found evidence of cardiovascular disease. Tire marks on the overpass
showed that brakes had not been applied before the crash, and a witness
reported seeing Frost slumped forward over the wheel.
