Police have named a Polish man they believe was killed in a fatal stabbing.
Ryszard Sawczyk, a 32-year-old married father-ofone, is thought to have been murdered at an address in Rugby, Warwickshire, last week.
Investigating officers are continuing to make a public appeal for help to trace his Polish housemate, 22-yearold Mariusz Szpyt, who disappeared from the semidetached property in Evans Road on Wednesday morning.
No body has been recovered but examinations at the scene reveal signs of what Warwickshire Police describe as "a significant degree of violence".
British officers have been liaising with the authorities in Poland to contact Mr Sawczyk's family and inform them of the ongoing inquiry.
Mr Sawczyk has a fiveyearold son and came to England from Szczecin, in the north of Poland, on May 31 this year to work in the local area.
Officers were only informed in the early hours of Thursday that there had been an incident at the property overnight between Tuesday and Wednesday.
Detective Superintendent Ken Lawrence said he believed Mr Szpyt left the house in a blue or black lefthand-drive Volkswagen Golf - Polish registration plate ZS 60262 - with Mr Sawczyk's body in the boot.
Staff at ports and airports across Britain remain on the look-out for Szpyt, who is described as white, 5ft 6in to 5ft 10in and stocky. He has short dark blonde or brown hair, which is receding, a round face and blue eyes and has a noticeable gap in his front teeth.
He was last seen wearing a light grey top, brown trousers and white Nike shoes and reportedly has a number of fresh cuts to his arms and hands.
Det Supt Lawrence said forensic examinations had continued throughout the day at the seven-bedroom house, in which several Polish and African men lived.
