A Tracy Fire Department Battalion Chief’s command vehicle stolen from the scene of an emergency medical call on MacArthur Drive shortly after 1 a.m. Monday was recovered by Manteca police some 30 minutes later with the help of a Manteca fire engine that slowed the vehicle at the AutoZone parking lot in the 100 block of South Main Street. Manteca firefighter Brian Swift said his crew had just completed a medical call in the 100 block of Maple Avenue behind the former location of the Bank of the West, now the India Merchandise Store, for a patient in a homeless encampment who was transported by ambulance to the hospital. They were in the process of turning their fire truck around when they ended up becoming involved in efforts to recover the stolen fire vehicle. Swift said he heard numerous sirens coming into the parking lot area with a number of police cars chasing a vehicle.
