Hi Danfun128,
While I'm afraid I don't have any leads for you, I do have a few suggestions:
First, do you know the name of the hospital in question? They might have a P.R. person who would have saved the info.
Second, there are a couple of companies that handle hospital security. Since the event in question was news-worthy, someone at one of those companies may remember and have a lead.
Third, I know you want a particular newscast, but is it possible that a newspaper article may have the same information?
Finally, I'd try the TV station's Facebook and/or Twitter account. That might be a faster way to get a reply. Failing that, if you live near the station, you could try going there and talk to someone. (I don't know how far they'll let you in, but it'd be worth a shot, especially if they know how much it means to you.)
I really hope this is at least somewhat helpful and that ultimately you find whatever you're looking for. Best of luck! :)
