A toxic combination of opiates and benzodiazepine, a drug used to treat insomnia and depression, killed Abraham Briggs. The 19-year-old man died Wednesday, the Broward County medical examiner's office confirmed. Briggs had a prescription for the antidepressant, but authorities are unsure how he obtained the others.

It's not clear how many people watched the suicide, but police are investigating the Web site moderator's role in the live video streaming of the suicide on Justin.tv. Investigators are also looking at comments on the discussion board at bodybuilding.com that linked to the streaming video.

Egging Briggs On

Police reports indicate some of the people watching Briggs at Justin.tv encouraged him to end his life, while others tried to talk the teenager out of it. Some were discussing whether or not it was a hoax, or whether he took enough pills to actually kill himself. Briggs had reportedly threatened to kill himself on the bodybuilding.com site previously.

The debate soon ended as a visitor to the forum notified the moderator about Briggs' post and the moderator called the police. Law enforcement traced Briggs' location to Pembroke Pines near Miami. But when they arrived at his house at 3:30 p.m., they discovered he was dead. Briggs started blogging at 3 a.m.

"There seems to be a lack of control as to what people put out on the Internet," Abraham Biggs Sr., the young man's father, told ABCNews.com. "There's a lot of garbage out there that should not be, and unfortunately this was allowed to happen."

Justin.tv CEO Michael Seibel commented on the situation in a formal statement: "We regret that this has occurred and want to respect the privacy of the broadcaster and his family during this time."

Deadly Prescriptions?

Biggs said his son had a prescription for benzodiazepine to treat a bipolar disorder. The young Briggs struggled with depression, but his father said his son seemed to be doing better.

While many are focused on Justin.tv's potential liability in streaming the video, Neil Byrne of Stop RX Foundation is focusing on the pharmaceuticals Biggs used to take his life. As Byrne sees it, the global Internet broadcast of Biggs' death is an example of the effects of mind-altering drugs.

"It is an outrage that these drugs continually get prescribed and the results continually are the same -- mass murder and suicide. You will probably get excuses from the three-headed monster -- the FDA, psychiatrists and big pharma -- that antidepressants should be accompanied by counseling," Byrne said. "You will not get any of these three taking responsibility for the lethal nature of these drugs."

According to Byrne, pharmaceutical companies continue to be free of responsibility. The next presidential administration is a cosponsor of the mother's act, he warned, so it is likely to get worse unless people decide enough is enough.

"Mothers and fathers need to speak up loudly against the overuse of these drugs and the passage of mother's act," Byrne said. "This young man's life was abruptly ended by a lethal dose of drugs he should have never taken and never needed. There are endless natural options to depression."
