MIAMI (Reuters) - A Florida teenager committed suicide by drug overdose in front of a webcam streaming live video to the Internet and some viewers may have egged him on, authorities said on Friday.

Abraham Biggs Jr., 19, was found in the bedroom of his home in Pembroke Pines, Florida, on Wednesday and an autopsy showed he died of a toxic combination of opiates and benzodiazepine, a drug used to treat anxiety and insomnia, the Broward County Medical Examiner's Office said.

"We have ruled it a suicide. Part of the terminal event was recorded on a website and there was streaming video," said Dr. Steve Cina, deputy chief medical examiner of Broward County.

A police spokesman said detectives were investigating the case but would not release any details.

Biggs had written blogs about his intentions and some of the viewers who were watching the event live may have goaded him on, Cina said.

"There is some indication of that, yes," he said.
