Cops say that Lisa Carr, 43, was released from Deaconess Hospital in Cincinnati around 11 PM Thursday.

Following Carr’s discharge, an ambulance driver flagged down a cop car to report that his vehicle–which he left running outside the hospital while dropping off a patient–had been boosted.

Police officers were quickly able to track the ambulance via its GPS signal and began following the vehicle on what became a 20-minute trek to Carr’s residence 10 miles from the hospital. The ambulance never topped 30 mph, according to a police report.
