Apparently there is. Dr. Manny talked about it this morning. But he mentioned that if that was true, then the police were negligent--they should have gotten him to an emergency room because they couldn't have known whether or not he was having a stroke or something more serious like that. My husband remarked that they probably didn't do that because they smelt alcohol on his breath, and sure enough, apparently one of the officers did report a "boozy" smell.
Dr. Manny on the radio now saying that if he did take Ambien .. most people don't remember after wards clearly of what they did
