Police have released a picture of the family they suspect has been murdered by a man who is now on the run and believed to have left the country.
Ndodana Mkhanyisi Tshuma is thought to have fled the UK after the discovery of the bodies of a woman and two children in Great Denham, Bedfordshire, on Monday.
The three victims are believed to be the man's wife, Nothabo Zandile Tshuma, 42, known as Zandile, and his daughters Natalie, 15, and Nala, five.
The 45-year-old suspect, who goes by the name Mark, is from Bedford and is a British citizen of Zimbabwean heritage.
He's thought to have flown from Heathrow to Zimbabwe on Saturday.
They had not been seen for several days when Bedfordshire Police forced entry to the house two days ago.
Detective Inspector Lee Martin appealed to the suspect to hand himself in.
In a message to the suspect, he said: "We are actively working with national and international agencies to pursue every available line of inquiry to track you down - and we will find you.
"Mark, unthinkable harm has been caused to those around you, and this has left your relatives and friends utterly devastated.
