>> sheriff's deputies report seeing talman drinking with friends on the beach prior to the accident. drinking is legal on siesta key beach. dr. chen is on a crusade to change that. >> 95% of the beaches in the state of florida and, in fact, across the country don't allow alcohol and public drinking. we've had petitions online, we've had discussions with the county commissioners. i don't think the residents here want to have alcohol associated with our beach. it would certainly be a tribute to donna, help us feel better about her death if those laws could be changed. >> once o'connor knows the whole story, he updates his post on youtube. >> i updated the notes on it so the people could see that it was resolved, not in a real happy way, but the mystery was solved anyway. >> rory and dr. chen have met a few times since that fateful day.
