"It was a big part of his life, it was his community. This is where he reached out," the teen's mother, Doreen Biggs, told CBS' The Early Show in an exclusive interview.
Only after police arrived to find 19-year-old Abraham Biggs dead in his father's bed did the Web feed stop Wednesday - 12 hours after the 19-year-old Broward College student first declared on a Web site that he hated himself and planned to die.
"I'm hurt, I'm angry that so many people could actually watch this and not think that it's there responsibility - not do anything about it - he was calling out for help," Doreen Biggs said.
"We do have a moral and social responsibility to each other," she said.
Biggs announced his plans to kill himself over a Web site for bodybuilders, authorities said. He posted a link from there to Justin.tv, a site that allows users to broadcast live videos from their Webcams.
A computer user who claimed to have watched said that after swallowing some pills, Biggs went to sleep and appeared to be breathing for a few hours while others cracked jokes.
Abraham's sister Rosalind Biggs Fanning agreed with her mother and said she was upset that the Web site's moderators didn't respond to her brother's pleas for help.
"All we can do is sit there and watch?" Rosalind said.
She added that there needs to be a standardized method for getting people who are online and in distress help.
After hours of inaction, eventually someone notified the moderator of the bodybuilding site, who traced Biggs' location and called police, Crane said. The drama unfolded live on the Web site which allows viewers to post comments alongside the video images.
As police entered the room, the audience's reaction was filled with Internet shorthand: "OMFG," one wrote, meaning "Oh, my God." Others, either not knowing what they were seeing, or not caring, wrote "lol," which means "laughing out loud," and "hahahah."
It is unclear how many people watched it happen. The Web site would not say how many people were watching the broadcast. The site as a whole had 672,000 unique visitors in October, according to Nielsen.
Biggs was not the first person to commit suicide with a Webcam rolling. But the drawn-out drama - and the reaction of those watching - was seen as an extreme example of young people's penchant for sharing intimate details about themselves over the Internet.
