The case against four men accused of murdering a man who was found dying in the back of a van has been adjourned.
Father-of-three Shaleem Amar, 33, of Sunningdale, was found in the van after it was stopped by police on the A30 in Sunningdale, Berkshire, on 17 November.
Robert Johnston, 56, Tom Johnston, 24, Ben Johnston, 26, and Shaun Matthews, 55, all of Cambridgeshire, were due to plead at Reading Crown Court.
But the defence has been given more time to consider expert evidence.
The hearing was adjourned and the men, who were all remanded in custody, are due to plead on 28 March.
A provisional trial, which is expected to last for up to six weeks, has been set for 16 May.
Tom, Ben and Robert Johnston, who appeared via videolink, are all from the village of Pampisford while Shaun Matthews is from Whittlesford.
A post-mortem examination showed Mr Amar died of head injuries.
Thames Valley Police referred the case to the Independent Police Complaints Commission (IPCC) after it was revealed Mr Amar was not discovered in the van for nearly 40 minutes after it was stopped.
But the watchdog said the actions of officers were reasonable in the circumstances.
