Two men have admitted the part they played in the drugs gang murder of a man in a Norwich car park.
Honorato Christovao, 54, was beaten to death after he was lured to the car park in Rose Lane in February 2011.
Ashley Brown Garraway, 22, of Newham, east London, admitted conspiracy to commit grievous bodily harm.
Neil Whitby, 40, of Borrowdale Drive, Norwich, pleaded guilty to conspiracy to kidnap. Two men were jailed for murder at Norwich Crown Court in March.
Spencer Yiadom, 22, of Saville Road, Newham, was jailed for 24 years.
Anton St Paul, also 22 and of Newham, was jailed for a minimum of 23 years.
Garraway, of Oxford Road, and Whitby have been remanded in custody and will return to Norwich Crown Court to be sentenced on 28 May.
Lucy Browne, 35, of Borrowdale Drive, will be sentenced on a date to be fixed for manslaughter.
She pleaded guilty at an earlier hearing.
The death of Mr Christavao, of Parmentergate Court in Norwich, was the result of a dispute between two drugs gangs known as the JJ group and the GBen Group.
Det Ch Insp Jes Fry said: "The guilty pleas of these two additional individuals is a welcome result. It has been a long, complicated investigation for all the officers involved in the inquiry.
"Both of the defendants had been identified before the previous trial, but it was the evidence of Browne, who is the partner of Whitby, which was the deciding factor which allowed us to bring charges."
