So...
I just heard back from the man who my friend and I found passed out on the sidewalk the other night. He's back home in Virginia, and doing OK, but...
When he woke up in the hospital yesterday morning, he had no idea how he got there, or that he had passed out on the sidewalk the night before. Apparently, there was no record of who brought him in the night before - no indication of an ambulance or police report on his discharge papers. He's been trying to call the hospital today, but can't get through to anybody who can really help him, so he'll try again in the morning. So, he kept asking me what I knew, if I knew anything about what had happened, and all I could really tell him was that we found him on the sidewalk, then called 911. I did bring up the fact that I noticed that there was no cash in his wallet, and he said that his watch was also missing. He then mentioned that some other pilots have dealt with similar situations, and that someone probably slipped something in his beer - he was at the Irish pub around the corner.
So, the mystery is almost solved, and I really am glad that I followed up and that he called me back.
So... Wouldn't there have to be some sort of indication of who brought him into the ER somewhere?
