THE man wanted in connection with the brutal murders of twin sisters and a frail elderly couple in North Yorkshire told a number of "spurious stories" to avoid detection, police say.
Sisters Claire and Diane Sanderson were subjected to a violent assault and a hammer was recovered from a flat in Camblesforth, North Yorkshire.
Detectives said Claire had been dead for a number of days when the bodies were found on Sunday but her sister Diane was seen the day before. They believe Mark Hobson, 34, may have killed girlfriend Claire and then lain in wait for several days for Diane. She eventually went to check on Claire.
Police revealed that Hobson had delayed the discovery of Claire by deceiving her parents in a phone call by convincing them her failure to contact them at an agreed time was not suspicious.
She had failed to contact them on the Thursday before she was found dead, as she had told them she would.
Hobson also arranged for his mother, Sandra - who yesterday made an emotional appeal for the former binman to give himself up - to drive him to York District Hospital in the early hours of Sunday.
Det Supt Javed Ali, of North Yorkshire Police, said: " He has provided an account to his mother which we believe was spurious and which she had been taken in by."
He was spotted on CCTV around the hospital at 2am. Just seven hours later James Britton, 80, and his wife Joan, 82, were found murdered at their house in Strensall, just three miles away.
Mr Ali said that, at 9.05am, the couple were visited by neighbours and were alive and well. Ten minutes later there were a number of sightings close to the Brittons' home of a man fitting Hobson's description.
