A man suspected of murdering his wife and two daughters has been named by police.
Ndodana Mkhanyisi Tshuma is believed to have fled the UK after the discovery of the bodies in Great Denham on Monday.
The 45-year-old, 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.
The three victims are believed to be his wife Nothabo Zandile Tshuma, 42, known as Zandile; and his daughters Natalie, 15, and Nala, five.
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.
"Mark, unthinkable harm has been caused to those around you, and this has left your relatives and friends utterly devastated," he said.
