Miami ? The father of a college student whose suicide was broadcast live over a webcam said Saturday he was appalled by the virtual audience that egged on his son and called for tougher regulation of Internet sites.

Abraham Biggs Sr. said those who watched and the Web site operators share some blame in his 19-year-old son’s death.

“I think they are all equally wrong,” he said. “It’s a person’s life that we’re talking about. And as a human being, you don’t watch someone in trouble and sit back and just watch.”

Police found Abraham Biggs Jr. dead in his father’s bed Wednesday, 12 hours after he first declared on the Web site for bodybuilders that he planned to take his own life. He took a fatal drug overdose in front of an Internet audience. Although some viewers contacted the Web site to notify police, authorities did not reach his house in time.

Biggs, who has said he was at work during the episode, said he had not known about his son’s online presence.

“I think after this incident and probably other incidents that have occurred in the past, they all point to some kind of regulation is necessary,” Biggs said. “I think it is wrong to have this happen for hours without any action being taken from the people in charge. Where were they all the time?”

The younger Biggs posted a link from the Web site to Justin.tv, which allows users to broadcast live with 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. Some users told investigators they did not take him seriously because he had threatened suicide on the site before.

Biggs Sr. said he believes the webcast was a cry for help.

“But rather than get help, he was ignored,” Biggs said. “I would not want to see anything like that on the Internet and not try and get help for that young man. I think that’s what the average person would do. Any normal person would do. I’m really appalled.”

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.
