I just watched this documentary called "The Bridge" - it was SO sad! Basically its a true life documentary that was fimed at the Golden Gate Bridge...they filmed continously for a year and caught quite a few people that were committing suicide by jumping off the bridge and then interviewed their family members.
There is also the account from survivor who jumped of the GG bridge. It was a haunting documentary to say the least...it was just really sad. I don't know if I would be able to film that and live with myself afterwards . I included the link from Google Video.
