A drug overdose patient being transported to the hospital startled emergency responders.

Shortly after 5 PM on Wednesday, emergency personnel and police responded to a call for a patient unconscious.

Upon arrival, they located a patient unconscious and not breathing – the result of an apparent drug overdose.

Emergency personnel successfully performed CPR on the patient, and then placed her into the ambulance.

Upon arriving at the MMCSC though, the ambulance door was opened and the patient just walked off.

Police are investigating.
