The death of a second man who was found inside the Los Angeles apartment of prominent Democrat donor, Ed Buck, has been ruled a methamphetamine overdose.

Timothy Dean, 55, was found dead on January 7 inside Buck's apartment.

He became the second man to die within a span of 18 months inside Buck's home.

'Toxicology results are back and the cause of death is an overdose,' Detective Quilmes Rodriguez of the Los Angeles County Sheriff's Department, said in an email to The Daily Beast.

'We've conducted several additional interviews with other witnesses and are pending the final two interviews,' the officer added.

Meth is the same drug that killed Gemmel Moore at Buck's home in 2017.

Last month, Buck was hit with a wrongful death lawsuit following Dean's death.

LaTisha Nixon filed legal papers in a Los Angeles court, alleging the 65-year-old West Hollywood political donor is responsible for the death of her son, Moore.

Buck has made more than $500,000 in political donations to both local politicians and national campaigns including Hillary Clinton's 2016 presidential bid.

Moore died of a crystal meth overdose in the donor's apartment in July 2017.

The LA Sheriff's Department opened a homicide investigation, but a year later the District Attorney, Jackie Lacey, declined to file charges against Buck, citing insufficient evidence.

Dean's death prompted an outcry from local activists for the wealthy Democrat's arrest.

Nixon's suit names Lacey and Assistant Head Deputy District Attorney Craig Hum as co-defendants, accusing them of wrongfully failing to investigate and prosecute Buck for murder.

The coroner ruled the death an accidental overdose and Buck has always maintained his innocence and denied any wrongdoing.

The lawsuit is seeking damages against Ed Buck for 'wrongful death, sexual battery, drug dealer liability, premises liability, negligence per se, intentional infliction of emotional distress and hate violence'.

In her legal complaint, Nixon cites evidence from several men who told police that they were 'forcibly injected with crystal methamphetamine by Mr. Buck'.

Buck's attorney, Seymour Amster, has previously denied any wrongdoing by his client, said Buck did not inject anyone, and called the allegations against Buck 'spurious'.

The lawsuit claims that Buck bought Moore a plane ticket from Houston to visit him at his apartment in July 2017, and that just hours after he landed, Moore was dead.

Police found the apartment 'littered with multiple syringes with brown residue, a scale, several lighters and torches, a straw with white residue, glass pipes with white residue and burn marks, plastic bags with white powdery residue and a clear plastic bag containing a crystal-like substance,' the legal papers say.

The documents claim Buck had 'previously solicited sex' from Moore 'would insist upon injecting Mr. Moore with crystal methamphetamine' then forcing him to watch hardcore gay pornography.

Buck also 'required Mr. Moore to masturbate and engage in other autoerotic sex acts for Mr. Buck's sexual gratification and pleasure,' according to the lawsuit.

'Until now, Ed Buck has avoided prosecution by the very same elected officials and law enforcement agents whose pockets he's been lining with hundreds of thousands of dollars in election campaign and legal defense fund contributions since 2007,' said Hussain Turk, one of Nixon's attorneys.

'Their refusal to criminally prosecute Ed Buck because he is white is an unjust and unequal application of the law.

'If the dead body of a blonde-haired, blue-eyed white man was found in the home of an older Black man, he'd be lucky to even make it to the police station alive,' Turk added. 'But on DA Lacey's and DDA Hum's watch, Ed Buck hasn't even been formally questioned for his involvement in the deaths of not one, but two Black men.'

Part of the evidence backing up the bereaved mother's lawsuit is Moore's journal, where he claims Buck injected him with crystal meth.

In one entry, Moore wrote: 'I honestly don't know what to do. I've become addicted to drugs and the worst one at that. Ed Buck is the one to thank. He gave me my first injection of crystal meth it was very painful, but after all the troubles, I became addicted to the pain and fetish/fantasy.

'My life is at an alltime high right now & I mean that from all ways. I ended up back at Buck house again and got munipulated into slamming again. I even went to the point where I was forced to doing 4 within a 2day period. This man is crazy and its sad. Will I ever get help?'

'Slamming' is a slang term for gay men injecting drugs such as mephedrone, GHB, or crystal meth.

In Moore's final entry on December 3 2016, he wrote: 'If it didn't hurt so bad, I'd kill myself, but I'll let Ed Buck do it for now.'

DailyMail.com has exclusively revealed accounts from two other men who claim Buck paid them to come to his apartment, strip and wear special underpants as well as other bizarre 'fetish' requests, and be injected by the wealthy donor with syringes of meth.

One man, Jermaine Gagnon, 28, said that during one such session in September last year, Buck gave him Gatorade secretly spiked with an unknown drug and then injected him with crystal meth as he lay incapacitated.

'My body was numb, I could barely move. All I felt was warm all over my body. It was a matter of seconds. My speech started slurring, I was in and out,' Gagnon told DailyMail.com.

'I saw him preparing the drugs at the table. He said 'you've got to watch'. I couldn't really stand up. I lay on the bed in the middle of the floor and was just laid out.

'He came over, he was like "I don't think you're high enough for me, I want you to do another point." That's when he pointed me. Immediately it felt like death took over my body. I don't know what it was. I felt like everything was going to end right there.

'I really thought I was the next person that was gonna be dead at Ed Buck's house.'

Gagnon said Buck paid twice to fly him to LA for a drug-fueled session, pushing more drugs on the young black man each time.

Another man wrote his family a detailed account of the many 'chemsex' sessions he had with Buck. The man has since died from an unrelated illness.

Buck called the black 30-year-old, who DailyMail.com is identifying only as 'Blake' at the request of his family, his 'crack baby', 'my n****r buddy', 'my straight n****r buddy', 'and 'black boy', according to Blake's account.

Blake claimed the Hillary donor paid to watch him defecate, strip-searched him before he left the apartment, and once even choked Blake when he refused to leave.

The former porn star told told his family Buck would trawl LA's Skid Row for young black men, and had an area he called 'the gates of hell' near the doorway to his apartment where he would photograph the men he paid for sex.

'Our hope is that this lawsuit will bring some modicum of justice for Gemmel and all of Ed Buck's victims,' said Nana Gymafi, human rights and criminal defense attorney and co-counsel for Nixon.

'If Ed Buck had any decency at all, he would have already come forward and apologized and offered to compensate Gemmel Moore and Timothy Dean's families for the terrible harm and trauma he has caused through his actions.

'But, Buck is not a decent human being, and so we are forced to bring this lawsuit to get some accountability and justice.'
