David Gest's bodyguard claims to have heard the star suffer a fatal heart attack during their last phone conversation - four days before his body was found.
The American entertainer was found dead in his London hotel room in April and according to Imad Handi - who was friends with David for 16 years - he received a silent phone call, which he believes was the 62-year-old trying to ask for urgent help, in the days before his body was found.
He told The Sun Online: "I answered the phone and was like, 'Hello, hello, hello?', and I heard something smash on the floor.
"Part of me froze and then the phone went dead. Knowing David and his OCD I thought, 'He's dropped something on the floor, he's going to hang up and clean it up. He'll call me back'. Unfortunately he didn't call me back.
"I did try and call that evening and on Saturday and there was no answer. I believe he passed away on the Friday."
Imad, 38, visited David's hotel room after being informed of his sudden passing and revealed he came across a number of clues that served to confirm his initial belief.
He said: "When I went to identify his body [in the hotel] there was a lamp that smashed on the floor beside him and I believe that was what I heard. He was crying for help.
"I reckon he was on the floor trying to make a phone call and couldn't speak. He was trying to make a noise of some sort. I believe he had a heart attack or a stroke.
"His clothes were on the bed ready for him to wear, the way he sets his clothes out every day. Everything was pointing at him getting ready to go and enjoy a day out."
