PEMBROKE PINES, Fla. -- A South Florida college student killed himself by overdosing on drugs in front of a live online audience as some computer users egged him on, some debated his method and others tried to talk him out of it, according to investigators with the Broward County medical examiner's office.

Abraham Biggs, 19, of Pembroke Pines, died Wednesday at his home from a toxic combination of opiates and benzodiazepine, a drug used to treat insomnia and depression, said Wendy Crane, an investigator with the Broward County medical examiner's office.

Abraham Biggs' Suicide Note

---

Authorities said the Broward Community College student is not the first person to commit suicide with a webcam rolling.

Biggs posted his webcam on a bodybuilding Web site. Published reports said that 1,500 people watched, some allegedly egging Biggs on, insulting him as he took pills and lay on his bed.

Someone finally notified a site moderator, who pinpointed Biggs' location and called police, but they arrived too late to save him, Crane said.

Biggs, who used the screen name "CandyJunkie" on the bodybuilding Web site, started blogging about plans to kill himself 12 hours before he was found lying dead on his bed. He posted a link from the bodybuilding Web site to Justin.tv, a site that allows users to broadcast live videos from their webcams.

Some users who read the blog told investigators they did not take him seriously because he had threatened suicide on the site before.

But Biggs' family was infuriated that neither viewers nor the site acted sooner to save him.

"When (police) came in, the webfeed stopped. So that's 12 hours of watching," said his sister, Rosalind Biggs, who said her brother struggled with bipolar disorder. "They got hits, they got viewers, nothing happened for hours."

"I think it's wrong. The first statement that I want to make is that should not have been allowed to continue," said Biggs' father, Abraham Biggs Sr. "Someone should have been monitoring and sought help for him right away."

The medical examiner's office said Pembroke Pines police officers found Biggs at 3:30 p.m. His last blog entry was submitted at about 3:30 a.m.

Authorities could not immediately verify the authenticity of a video posted online that shows a gun-wielding officer entering a bedroom where a man is lying on a bed, facing away from the camera. The officer peers over to look at the man, then begins to examine him as the camera lens is covered. The video matches Crane's description of events.

Rosalind Biggs described her brother as a friendly, social, outgoing person who struck up conversations with Starbucks baristas and enjoyed taking his young nieces to Chuck E. Cheese.

"It boggles the mind," she said. "We don't understand."

Abraham Biggs Sr. told Local 10's Jeff Weinsier that this never should have happened, that someone watching should have stopped it.

"That's sickening to think of," Abraham Biggs Sr. said. "I wouldn't wish that on anybody's child. He was a nice boy, a very good kid."

Condolences poured in to Biggs' MySpace page, where the mostly unsmiling teen is seen posing in a series of pictures with various young women.

In a statement, Justin.tv CEO Michael Seibel said: "We regret that this has occurred and want to respect the privacy of the broadcaster and his family during this time."

The Web site declined to release information on how many people were watching the broadcast. The entire site had 672,000 unique visitors in October.

Messages left with the bodybuilding Web site were not immediately returned Friday.

A spokesman for the Pembroke Pines police said they were investigating but declined further comment.

Crane said she knows of at least one other case in which a South Florida man shot himself in the head in front of an online audience, although she didn't know how much viewers saw. In Britain last year, a man hanged himself while chatting online.
