BELLWOOD, Ill. (AP) — An autopsy report shows that an ambulance driver had cocaine in his bloodstream when he crashed into a suburban Chicago building, killing himself, a co-worker and a patient.

The Cook County medical examiner’s office found that 51-year-old emergency medical technician James Wesley also had significant cardiac disease at the time of the March 31 crash in Bellwood.

The autopsy couldn’t determine whether a heart attack or cocaine intoxication led to the crash.

Wesley died instantly in the crash, and 50-year-old EMT Prentis Williams and 48-year-old dialysis patient Larry Marshall Jr. were also killed.

County officials say the ambulance was unlicensed. A lawyer for the now-defunct ambulance company says Wesley took the vehicle without permission and apparently freelanced scheduled patient transports.
