Eight months on from the murder of Stevenage doctor Karen Woo while treating villagers in war-torn Afghanistan, her family are still looking for answers about her death, while a film about her life is to be aired on prime-time television.

The investigation into the attack on the 36-year-old’s medical convoy in a remote area of the country, which left her and nine colleagues dead, is being led by the FBI.

Karen’s parents Lynn and Tehaun, who live in Brixham Close, met North East Beds MP and Foreign Office minister Alistair Burt at Westminster at the end of last month for an update on the investigation.

Lynn said: “There was no obvious progress to report although since the meeting I have heard that the FBI may have made more progress than was at first thought. The meeting was helpful though and Alistair Burt was sensitive but practical in his attitude.”

The former St Nicholas and Barclay school pupil had not only been treating the sick on her fourth humanitarian visit to the country, she was also arranging for medical supplies to be flown into Afghan hospitals as well as recording a documentary about the lives of ordinary Afghanis.

This footage will form part of a documentary on Karen’s life to be screened on ITV at 10.15pm on Sunday May 22.

“The film considers something of what made Karen who she was and attracted her to a place like Afghanistan,” Lynn said. “It is not of course the documentary she had been attempting to make though it does incorporate one or two bits of hers. They have also tried to include something of the message she wanted to put out about the state of healthcare there.”

A central focus of the film is the relationship between Karen and her fianc� Mark Smith, known as Paddy. Karen died a month before they were due to marry.

“It dwells a lot on her relationship with Paddy and his grief,” Lynn added.

A charitable foundation has been set up by the family in Karen’s name to help raise and channel funds into charities working to improve the health of ordinary Afghanis.

Over the Easter weekend, friends Mark Hamilton and Pete Zebedee, inspired by Karen’s work will be tackling a 125 mile charity kayak race from Devizes in Wilshire to Westminster to raise funds for the cause.
