Two of the six men jailed for life for the kidnap, torture, rape and murder of Mary-Ann Leneghan are appealing against their convictions
Jamaile Morally, 22, and Indrit Krasniqi, 18, were jailed for life in April for killing the 16-year-old in Reading, Berkshire, on 7 May 2005.
Ringleader Adrian Thomas, 20, who was also jailed for life, is appealing against his 27-year tarrif.
All six men were also convicted of the attempted murder of Mary-Ann's friend.
The 19-year-old survived being shot in the head.
The remaining three members of the London gang - Michael Johnson, 19, Joshua Morally, 23, and Llewellyn Adams, 24 - have not lodged appeals.
Thomas, of Battersea, Johnson, of Southfields, and brothers Jamaile and Joshua Morally, of Balham, were all told during sentencing at Reading Crown Court that they must serve at least 27 years.
Adams, also from Balham, and Krasniqi, of Chiswick, were ordered to serve at least 23 years.
During the case, jurors heard how the girls were drugged, raped and tortured with cigarettes, knives, a metal bar and boiling water for three hours.
They were then driven to Prospect Park to be executed in a revenge killing for an earlier gang attack on Thomas.
