Police officers have been commended for their work during the inquiry into the disappearance of murdered girls Holly Wells and Jessica Chapman.
Holly Wells and Jessica Chapman were murdered in August 2002
Tom Lloyd, Chief Constable of Cambridgeshire Police, gave awards to 78 police officers and 39 police staff.
He also gave awards to 11 members of the public and 21 "outside contracted staff" involved in the inquiry.
The parents of Holly and Jessica attended the awards ceremony that took place in Cambridge.
Also at the presentation was Her Majesty's Chief Inspector of Constabulary, Sir Ronnie Flanagan.
Holly and Jessica, both 10, vanished while walking near their homes in Soham, Cambridgeshire, on 4 August , 2002.
Their bodies were found by a gamekeeper in an overgrown ditch at nearby Lakenheath, Suffolk, on 17 August.
The girls' disappearance triggered one of the biggest missing person inquiries seen in the UK.
School caretaker Ian Huntley was convicted of murdering the girls, at his home in Soham, following a trial at the Old Bailey in December 2003.
His former girlfriend Maxine Carr was convicted of perverting the course of justice.
'Publicity and controversy'
On Wednesday night Chief Constable Lloyd said: "These tragic events have attracted huge public interest and, sometimes, controversy.
"I understand that and I also understand that it is now right to acknowledge the many people who were deeply affected by, and the many people who contributed to, what was a difficult, demanding and ultimately successful investigation and prosecution."
He explained that those receiving recognition "were representative" of the many people involved in the inquiry.
"I know that the families of Holly and Jessica are very keen to recognise the efforts of all those involved," he said.
A police spokeswoman said awards presented included Senior Investigating Officer Good Work Certificates, Chief Constable's Letters of Recognition, Chief Constable's Good Work Certificates and Chief Constable's Commendations.
