Police are still looking for a Washington man they believed murdered his three young daughters one week ago.Travis Decker, 32, is wanted on kidnapping and first-degree murder charges for killing his daughters aged nine, eight and five, according to the Wenatchee Police Department in Washington state.

Officials believe Mr Decker, who they say is an outdoorsman and may have gone to mountain survival school as part of his military training, is hiding in a remote part of the mountainous and wooded state, making the search for him difficult.He has been said to "pose a significant risk, if approached". Police have not provided a possible motive.The girls, Paityn, Evelyn and Olivia, died from apparent suffocation in a remote campground, earlier this week, according to police.

Their mother reported them missing on 30 May after Mr Decker failed to return his daughters to her following a visit. He also did not take her phone calls.A few days later, on 2 June, police found the girls' bodies near a campground.

Police also found Mr Decker's cell phone at the campground but he was no longer there. His truck, which he was believed to have been living in, was also found nearby.

"I don't think any motive would be acceptable. And clearly it's not the decision of a sound mind," Chelan County Sheriff Mike Morrison said at a press conference on Wednesday, where he made a public plea to Mr Decker to turn himself in.The BBC was only told about the IPCO issue last week, with further information then provided after MI5 abandoned an attempt to keep applying its NCND secrecy policy on X's agent status.

, a panel of senior judges is considering what to do next about MI5's false evidence.MI5's internal review into the false evidence said it was a result of mistakes, poor memories and bad record-keeping.

The BBC said there is evidence of lies by MI5 officers, the internal inquiry was lacklustre and MI5 tried to keep damning material from the court.IPCO said its investigation of how MI5 had managed Agent X found a "critical failure to create and maintain accurate documentary records; a finding which was reinforced in the final report due to MI5's inability to produce any contemporaneous records and the length of time taken to respond to our requests for supporting evidence".
