In a posting where the 18-year-old slammed the 66-year-old Rambo star's current wife Jennifer Flavin, he also said the action man had cut Sage out of his life, devastating the aspiring filmmaker.

He said: 'What did he do wrong, say happy birthday? Neither you [Stallone's wife Jennifer Flavin] or he could return a phone call, which is all he wanted, his father.

'I know you don't care what happened, but you'll care when you’re squirming under the burning magnifying glass of public opinion. You people make me f****** sick.'

Edd, who is the son of Stallone's half-sister Toni Ann, also went on to make a withering attack to 43-year-old former model, who married the Rocky favourite in 1997.

Edd said: 'Jennifer Flavin, you won. You tore this family apart and got your trophy, Congrats! 

'Like you told my family, "I'm Sly's family now, he doesn't [need] you anymore.

'Lets see how much he needs you after this.'

Tragic: It is believed the aspiring young filmmaker died of an accidental drugs overdose

Sage's mother Sasha Czack,split with Stallone in 1985 after 11 years of marriage.

According to reports she got a $12 million divorce settlement from the filmmaker.

A source said: 'Sasha has been inconsolable. She’s totally devastated. Her children are her life.'

Meanwhile it has emerged officers investigating the death want to talk to several doctors that prescribed him medications.

It follows Los Angeles Police Department Robbery and Homicide division has taking over the case.

A source told RadarOnline: 'Detectives from the LAPD are in the process of going through evidence recovered from Sage's house and will be contacting the doctors that prescribed the medications found there.

'There was more than one doctor that Sage was seeing in the days leading up to his death. 

'Cops want to establish a timeline of events leading up to Sage's death and they want to know what his medical history was.'

While prescription bottles were found at the scene, no suicide not was found and it is believed his death was accidental.

On Sunday night, Sylvester issued a statement asking 'people to respect my talented son's memory and feel compassion for his loving mother Sasha,' and for the media to stop 'the speculation and questionable reporting.'

He added: 'When a parent loses a child there is no greater pain. This agonizing loss will be felt for the rest of our lives.

'Sage was our first child and the center of our universe and I am humbly begging for all to have my son's memory and soul left in peace.' 

An autopsy and a toxicology test were completed Sunday, but the results of the latter will not be released for weeks.

Meanwhile a photographer who did a feature on Sage in May said he was not surprised about the death, though he said the young filmmaker was far from suicidal.

Girls and Corpses snapper Mark Berry told RadarOnline: 'I saw nothing to suggest that he was in a suicidal mood. He was telling me about how he wanted to shoot a film, he seemed hopeful for the future and making work plans.

'My impression was that he was a very talented character who seemed under the influence of a pharmaceutical medication, he wasn’t a wreck but he was just a little spaced out.

'I wasn’t entirely shocked when I heard (of his death), my initial thought was that he had an accidental overdose, or that his body just packed up.'
