George Michael's cousin suspects the singer died of an accidental drugs overdose.
"One thing is for sure this was not an act of suicide", Andros added. Speculation has only worsened as his family has refused to comment or provide details of the 53-year-old's death last month. Authorities announced that Michael's autopsy results were "inconclusive", and said there would be further tests conducted.
"I believe he had suicidal thoughts, because his mental health was all over the place".
He claimed his cousin would not have committed suicide but said his friends "should have looked after him".
Speaking to the BBC's Victoria Derbyshire programme, Mr Georgiou said: "I just think he took too much of something, mixed with antidepressants and other drugs he was on - with alcohol".
Referring to his cousin by his nickname "Yog", Mr Georgiou wrote: 'I have been trying to hold back on this tweet I saw almost 10 days ago but the more I am reading and the more I am finding out about Fadi I just can't keep my mouth shut any longer.
Mr Georgiou said he believed Michael's death was an accident.
He added the Faith star, who was admitted to a rehab facility in Switzerland in 2015, had been taking steps to conquer is drug demons but he believes he was "dragged back into the dark side".
Mr Georgiou - who became estranged from Michael in 1998 - paid tribute to the "incredibly generous" superstar who was "one of the nicest people you could ever meet". I want to get to the truth of what happened, exactly what was in his blood at the time, who gave it to him, what did he have it again'.
In a Facebook post, Georgiou wrote, "They never lived together".
Days after George's death, a string of tweets were sent from Fadi's account claiming George had attempted suicide many times. If I was around this would never have happened and I have to live with that the rest of my life.
Following several reports of acts of kindness performed by Michael that have come to light since his death, Mr Georgiou spoke of how he and the singer used to drive around the West End in London on Christmas Eve "with two Range Rovers full of food. and feed all the homeless".
Ortiz also said Michael wasn't happy with his life.
Although Fawaz later said that his Twitter account had been hacked and he's never written the messages posted on January 1 that were later deleted, Georgiou addresses some of the claims made in the tweets.
