A 26-year-old man has been jailed for life for murdering his neighbour by stamping on her at her home.
Jolanta Dumciuviene was killed in her room at a shared house in Milner Road, Wisbech, Cambridgeshire, in May 2009.
The 38-year-old's body was found beneath a mattress three days later after her friends became concerned.
Tomas Acas, who was told he must serve at least 16 years in prison. He was convicted of murder at Cambridge Crown Court in January.
The court heard Acas lived next door to Mrs Dumciuviene and also worked with her at the Del Monte canning factory in Wisbech.
She had gone missing after a barbecue at Acas's home.
A post-mortem examination revealed she died from injuries to her chest, including a ruptured liver, a number of broken ribs and internal bleeding, that could have been caused by stamping.
She also had extensive damage to her throat.
Acas had denied murder but the court heard that his blood was found on her bed.
Police said they had not established a clear motive for the murder.
Acas's girlfriend, Airina Matulaityte, 24, also of Milner Road, was jailed for two years after previously admitting perverting the course of justice.
She lied to police about Acas's movements on the night in question, delaying his arrest and leading to a man being arrested who was later released without charge, the court heard.
Speaking after the case, Det Supt Jeff Hill said: "Our thoughts are with Jolanta's husband, who attended most of the trial, and her children back in Lithuania.
"Jolanta came to this country to earn money for her family but had the misfortune to cross paths with a brutal killer.
"Acas will now have plenty of time to think about the devastation he has caused by committing such a despicable crime."
