Police are urgently seeking Mark Tshuma, a £100,000-a-year IT executive, who is believed to have fled to Zimbabwe after the alleged murders of his estranged wife, Zandile Tshuma, 42, and their two daughters, Natalie, 15, and Nala, 5. Their bodies were discovered on Monday at the family's home near Bedford.

CCTV footage captured Tshuma at Heathrow Airport on Saturday, the day before the bodies were found, boarding a flight to his native Zimbabwe. Bedfordshire Police have stated that "criminal investigation knows no borders" and are working with national and international agencies to locate him. Detective Inspector Lee Martin appealed directly to Tshuma to "do the right thing, come forward and hand yourself in to local authorities."

Friends of the couple indicated that Zandile and Mark Tshuma were in the process of divorcing and had recently had their home valued as part of their separation. One friend reported that Tshuma had expressed an unwillingness to divorce, stating he could not live without his wife and children. Another friend described their marriage as having broken down, citing Mark Tshuma's controlling behavior and Zandile's desire to start a new life with their daughters.

Just hours before the alleged murders, Mark Tshuma was reportedly seen with his estranged wife at their daughter's school sports day. A friend described him as appearing normal and looking forward to the event. Another parent confirmed their attendance together, noting that their impending divorce was known.

Zandile Tshuma was an accomplished director specializing in financial crime, fraud investigations, and anti-money laundering. She previously worked in global banking and consulting. Natalie was a student at the £20,000-a-year Bedford Girls School, and Nala attended Pilgrims Pre-Preparatory School.

Headteachers from both schools issued statements mourning the loss of the students. Mrs. Gemma Gibson, Headmistress of Bedford Girls' School, remembered Natalie as a "bright and accomplished" student, talented in dance, music, and sports. Jo Webster, Headteacher of Pilgrims Pre Prep School, described Nala as a "much-loved member of our school community who brought joy to those around her."

The Khumalo family, Zandile's relatives, released a statement expressing deep sadness and gratitude for the support received, requesting privacy during this difficult time and stating that funeral arrangements are pending official investigations.

The family lived in a detached house in an affluent area of Bedford. Police forced entry on Monday after concerns were raised about the occupants' welfare. Authorities are continuing their investigation into the circumstances surrounding the deaths.
