Gemmel Moore, 26, was found dead in West Hollywood, CA on July 27

A 26-year-old man was found dead at the home of a well-known Democratic party donor late last month of a drug overdose.

The incident occurred on July 27 around 7.22pm at the West Hollywood home of Ed Buck, a high-profile political activist and wealthy contributor to the California and Los Angeles County Democratic Party.

The Los Angeles County Coroner declared Gemmel Moore's death an 'accident,' due to a 'methamphetamine' overdose, the WeHo Times publication reported.

But Moore's family believes that foul play was involved in the hours between Gemmel's arrival at Buck's home and his fatal overdose.

During a phone interview with the WeHo Times last week, Gemmel Moore's mother, LaTisha Nixon, said that her son had been involved with sex-work for the past few years.

'I called one of my son’s friends and was like, "who the hell is Edward Buck?'" Nixon said, speaking from her home in Spring Texas. 'And my son’s friend was like, "oh my God, that’s that white guy, that wealthy white politician guy… he was like "oh my God…’”

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

Buck became a successful businessman, pioneering in computer technology, specifically in electronic information services, in Arizona before moving to Los Angeles.

He was also a prominent AIDS activist in the community, according to asmartvote.org profile in 2007.

During Nixon's conversation with her son's friend, a darker picture of Moore's life began to emerge, with Buck allegedly playing a role.

'When he calmed down, he told me that Ed Buck was one of my son’s clients and that Ed Buck was one of his clients as well,' Nixon said. '[Buck] would have my son to go out to… Santa Monica Boulevard looking for young gay black guys so he could inject them with drugs, see their reaction and how [they] would react and take pictures of them.'

A phone call place to Buck for comment was not immediately returned. Buck is not a suspect in Gemmel Moore's death or any police investigation at the moment.

Nixon said that investigators with the West Hollywood Station of the Los Angeles County Sheriff’s Department notified her that no drugs or paraphernalia was found at Buck's home following her son's death.

An unidentified source who claims that he and Gemmel Moore shared Buck as a client told the WeHo Times that the former Buck also supplied him with drugs.

In one account, the anonymous source said that Buck asked him if he’d ever 'slammed,' a street term for intravenous meth use.

'I told him no, and that would take more money,' the source said, describing Buck’s reaction as 'excited,' adding he seemed to 'get off on getting you higher and higher.'

Nixon told the WeHo Times that her son's troubles may have had their start over a year ago, when he gave her a call in a panic.

'He filed a police report because he said that Buck had held him in his apartment or whatever and had shot him up with a needle with something he didn’t’ know what it was,' Nixon said,

'He called me crying. Three minutes on the phone hollering and I’m like "What the hell is going on?"'

'He said "This man, he shot me up with something I don’t even know what it is," and I’m like, my son is having a breakdown or episode. But he sent me pictures of his arm, his arm was red.'

The WeHo Times reported that at the time of publication, they had yet to obtain a copy of the police report.

No pictures of the alleged red markings on Moore's arms have been produced, said WeHo.

'Gemmel got scared and at the urging of relatives and few close friends who knew of these outrageous encounters; my son came home to me in Texas to get away,' Nixon continued. 'Yes, my son was an adult and didn’t live a fairy tale perfect life, but he didn’t deserve to die this way.'

Buck in 2015 gave Hillary Clinton $2700 and another $250 a year later, the WeHO Times reported, adding that Buck has also given thousands of dollars to Democratic incumbents in the state.

Other photographs found on his Facebook page show him with celebrities and high-profile California politicians, including Governor Jerry Brown.

The WeHO Times said that it placed numerous phone calls and emails to Buck, all of which has gone unanswered.
