A probe has been launched into the death of man at a prominent Democratic donor's home after it was previously ruled an accidental meth overdose.

The circumstances surrounding the death of 26-year-old Gemmel Moore are being questioned after people came forward with 'incriminating information' about Ed Buck, whose West Hollywood home Moore was found dead in on July 27.

Buck, 62, who has given money to names such as Hillary Clinton and Jerry Brown, has been accused by other escorts of instructing them to ingest dangerous amounts of drugs for pay.

Buck's attorney has repeatedly denied the accusations.

The LA County Sheriff's Office, at a city council meeting on Monday, said it was investigating the death but needed the cooperation of other alleged victims.

'Ed Buck has been soliciting young, gay black men,' Moore's mother, LaTisha Nixon, told reporters outside the city council meeting.

'He has them wear these long white under-johns. He takes pictures of them. He hits them up with meth. The more meth that they smoke and inject, the more money that he gives them.'

During the meeting, Nixon asked the council to put pressure on agencies handing the investigation - even suggesting immunity to other potential victims if they come forward with information about Buck

'I just want you guys to please put pressure on whoever needs pressure, so that these people can get immunity and I can get justice for my son,' she told the council.

'I'm asking for justice for my son - regardless to the fact of whatever he did. He still was my son. He still was a person.'

One alleged victim, who remained anonymous, told KTLA on Friday that Buck has instructed escorts to ingest drugs so he can watch their reactions.

'He gets his thrills just based off you getting high,' he said. 'He wants to see your reaction. He wants to see how can you take it - if you can handle it or not.'

A one-time registered Republican, Buck began getting involved in Southern California politics in the early 1990s.
