A man went Christmas shopping with his mistress hours after beating his wife to death, a court has heard.
Jonathan Palmer, 52, denies killing his 57-year-old wife Melinda at their home in Wadborough in Worcestershire on 22 December.
Worcester Crown Court heard Mr Palmer told his mistress he would visit her on that date and phone records suggest he left his home after his wife had died.
Tests showed a bloody fingerprint belonged to Mr Palmer, jurors heard.
It is alleged that he opened drawers and cupboards at their home to make it look like burglars had broken in.
Motorway CCTV images also supported the allegation he left after his wife's death, the court was told.
Mr Palmer's mistress, Jackie Marshall, lived in Worksop, Nottinghamshire. The prosecution allege he made up an alternative route north to police to make them think he left earlier.
Prosecutor Stephen Linehan QC said there was only one possible explanation for the lies and that was murder.
The trial continues.
