Three teenagers are facing life sentences for the brutal murder of divorcee Gary Rae.
William Devall, Luke Jones and Ahmet Gordon will find out the minimum time they will have to serve when they are sentenced on June 2.
Devall, 19, Jones, 18, and Gordon, 16, were convicted of murdering the father-of-two on Wednesday.
A judge yesterday lifted a ban preventing Gordon, of Swan Road, Hailsham, from being identified because of his age.
Shane Challice, 19, and a 17-year-old juvenile have been cleared of taking part in the killing outside Mr Rae's flat in High Street, Hailsham.
The jury at Hove Crown Court is still considering its verdict on a sixth teenager who denies murdering Mr Rae.
Jason Jackson, 18, of Albert Road, Polegate, has admitted he was there when Mr Rae was attacked but said he did not join in the attack.
The jury heard that Devall was jealous of his ex-girlfriend Amy Heaseman, 18, visiting Mr Rae's flat with other teenagers.
He wrongly believed that she was sleeping with him and assaulted her after she left the flat the day before the killing.
Devall turned up at a party at Shane Challice's flat in South Road, Hailsham, armed with a baseball bat on May 29.
He urged the others to go with him and boasted that he would turn Mr Rae into a cabbage.
Devall and Jones, both of Meadow Road, Hailsham, inflicted horrific injuries on Mr Rae with baseball bats.
Gordon, who knew Mr Rae, lured him down from his first floor flat by calling his name and saying he wanted to talk to him.
Witnesses said they boasted after the attack about what they had done.
Devall tried to kick his way out of the roof hatch of a prison van as it left Lewes Prison, The Argus can reveal.
Officers quickly restrained him but asked for extra security measures to be granted when taking him to and from Hove Crown Court.
Judge Anthony Scott-Gall agreed to their request for Devall to be handcuffed for the daily journey during the ten-week trial.
He was also ordered to wear an escape suit rather than his own clothes while he was being transported to and from prison.
The decision was taken in a private hearing in chambers and the move was kept from the jury to prevent it influencing their verdict.
The escape suit's large bright green and yellow squares has HM Prison in large letters written across the back.
It is designed to make prisoners who pose a security risk highly visible and easier to track should they escape.
Devall was allowed to change back into his everyday clothes before he appeared in the dock during the trial.
But he was ordered back into the escape suit and handcuffed before he was returned to Lewes each night.
Former girlfriend Amy Heaseman, 18, told the court about Devall's violent jealousy of her.
She had watched the attack with a 17-year-old friend from Mr Rae's bathroom window.
She said: "Will treated me very bad.
"I had walked out on him two weeks before he did this because he was hitting me.
"Will shouted at me that I was sleeping with Gary but I wasn't.
"He said he was going to f****** kill him."
The court heard that Devall drank heavily and took drugs almost daily before the killing.
He told medical experts that he spent most days looking for cannabis to smoke and had taken crack cocaine, heroin and ecstasy.
But it was his heavy drinking that led psychiatrists to conclude that Devall was suffering from a brain disorder when he killed Gary Rae.
He began drinking when he was just ten and was a binge drinker by the time he was 13.
Devall said at times he was drinking between eight and 25 cans of lager and half a bottle of vodka a day.
He admitted that he had been drinking and smoking cannabis before the gang set out to find Mr Rae.
The trial continues.
