A man stamped his neighbour to death and then returned to the scene of the crime two days later to move her body, a court has been told.
The body of Lithuanian Jolanta Dumciuviene was found fully clothed under a mattress at a house in Wisbech, Cambridgeshire, in May 2009.
Neighbour Tomas Acas, 26, who is also Lithuanian, denies murder.
Prosecutors told Cambridge Crown Court the victim was killed on 4 May and the body moved to the Milner Road address.
Mrs Dumciuviene was killed in her room at a shared house in Wisbech, Cambridgeshire, and not found by friends for three days, prosecutor David Matthew said during a trial at Cambridge Crown Court.
A pathologist said the cause of such injuries could have been "someone stamping on her", jurors were told.
Mr Matthew said evidence suggested that Mr Acas - who worked with her at a Del Monte canning factory in Wisbech - had murdered her on 4 May then tried to hide her body under a bed on 6 May.
Mrs Dumciuviene, whose husband and children live in Lithuania, was found on 7 May after friends became concerned about her disappearance.
Mrs Dumciuviene disappeared on 4 May after a barbecue at Mr Acas's home, jurors were told.
Mr Acas had also tried to use Mrs Dumciuviene's cash machine card and had given police different "stories" about his whereabouts, he added.
Mr Matthew told the court that evidence pointed to a timetable of events.
"It seems pretty clear she died on the evening of 4 May, Tuesday," said Mr Matthew. "The tidying up? ... The obvious time was Thursday morning."
He said Mr Acas's blood was found on Mrs Dumciuviene's bed.
"Maybe a nick or cut... when moving the body," added Mr Matthew.
"Let's see if Tomas Acas wants to go into the witness box and tell us how blood got there?"
The trial continues.
