Update on all involved
My aunt unfortunately was at JFK Medical Center for a time as she too was in a coma, just rooms away from Sean, his mom always seemed positive and would even wave at us when we came by (she probably had no idea I knew her from this special which I saw months after my aunt was brought to JFK) I only bring this up, to show that I have some insight on all involved and that I visited JFK several times.
Al'Khan Edwards sadly passed away and is shown in the film.
Sean died January 27, 2009 and there's a fund to his name which raises funds to JFK Medical Center
Tom though still with lingering effects, has had steady improvements as time has gone on, and he did get married to Lynda
Roxy has made a significant recovery and you can see what she looks like now on facebook. I'd say the page, but out of respect of her and her privacy, I don't want to bring attention that she may not want.
