March
The CPS confirm the men will not be charged with Claudia’s murder, following a study of the case put forward by detectives, citing there was “insufficient evidence” to prove that any of the men had any involvement in Claudia’s disappearance”.

Joan Lawrence said she was “absolutely devastated” by the announcement, which came a week before the seventh anniversary of Claudia’s disappearance, and Det Supt Dai Malyn, pictured below, said the decision was “disappointing and frustrating”.

The Northern Echo:

Peter Lawrence said he was disappointed with the decision, but “prosecution and even conviction would not bring Claudia back to us and may well not have resulted in revealing where she is buried, if she was murdered”.

Reflecting on the decision, Det Supt Malyn said: “I am left with the inescapable conclusion that this case could still be solved if only people were honest with us. The fact that they are not is agonising for Claudia’s family and they should be ashamed of themselves.”

Reports in the national press claim murderer Christopher Halliwell, pictured below, from Wiltshire - who killed Becky Godden in 2003 and Sian O'Callaghan in March 2011 - could have murdered others, including Claudia.

The Northern Echo:

The speculation is based on the suggestion Halliwell, who was given a whole life order - meaning he will never be released - had a relative who lived close to Heworth in 2009. North Yorkshire Police said this was incorrect - the relative died in 1992, and there were no known links, stating "this type of speculation does not help the family".

2017

January
Police announce the investigation, which by this time had cost £1m, was being scaled down to a 'reactive phase', and would only review any new and compelling information that comes to light.
