The three were convicted of murder in February
A second member of a gang of youths convicted of kicking father-of-three Garry Newlove to death is to appeal against his sentence.
Stephen Sorton, 17, of Warrington, was jailed for life in February for kicking Mr Newlove "like a football" and ordered to serve a minimum of 15 years.
The Crown Prosecution Service said it had had notification from the courts of his intention to lodge an application.
Another youth Adam Swellings, 19, of Crewe, lodged an appeal bid last month.
Swellings, the ringleader of the gang that attacked Mr Newlove, was jailed for life at Chester Crown Court in February this year and was ordered to serve a minimum of 17 years behind bars.
A third member of the gang - Jordan Cunliffe, 16, formerly of Warrington - was also jailed for life and ordered to serve a minimum of 12 years for Mr Newlove's murder.
It is not yet known if he plans to appeal.
Mr Newlove, 47, a salesman with a plastics company, left his home in Warrington, Cheshire, on 10 August last year after the gang had vandalised his wife's car.
The court heard he was kicked "like a football" in front of his terrified wife and daughters.
Mr Newlove's murder sparked outrage and a national debate about Britain's yob culture.

It emerged, after the trio were found guilty of Mr Newlove's murder on 16 January, that Swellings had been released from custody for an assault just hours before the attack.
He was freed on bail on condition he stayed away from Warrington but he never left the town. Instead he met up with accomplices Sorton and Cunliffe and began a drink and drugs binge.
Mr Newlove's daughters Zoe, 18, Danielle, 16, and Amy, 13, saw the attack on their father.
Following the guilty verdicts in January, Mr Newlove's widow, Helen, 44, spoke out and pledged to campaign to make Britain safer.
She said: "I am determined to carry on for the sake of my wonderful husband Garry. He will not have died in vain."
