The 52-year-old chief constable of Cambridgeshire police, Tom Lloyd, came under considerable pressure during the Bichard Inquiry.
Tom Lloyd said "nothing could redress" what happened to the girls
After Ian Huntley's conviction for the murder of Holly Wells and Jessica Chapman in Soham, his Humberside counterpart faced criticisms for failing to keep records of previous allegations against Huntley.
But during the inquiry it emerged Mr Lloyd's force had not even asked Humberside to do a vetting check.
He admitted while giving evidence that every stage of the vetting process by his force had suffered from "disturbing" and "significant"
He gave evidence to the inquiry on 11 March wearing a full police uniform, watched by the parents of Holly Wells.
In his concluding statement he said: "Nothing can redress what happened to
Holly and Jessica, their families and friends.
"But as I think of that... it gives me the resolve
to make sure that what I do and what my colleagues do will be designed to ensure that what has happened by way of failings never happens again."
Mr Lloyd is married with four children, and was educated at New College, Oxford University, where he read philosophy and psychology from 1971 to 1974.
The year he graduated he joined the Metropolitan Police and spent his
early career at Marylebone and West End Central police stations in London.
His time at the Met saw him in a number of uniform and specialist roles.
From 1992 to 1996 he was chief superintendent in Central London and in 1996 was promoted to commander.
As director of strategic co-ordination he was responsible for corporate, strategic and annual planning, liaison with the Home Office and the development of information management.
In January 2000 he transferred to the Cambridgeshire Constabulary as deputy chief constable and was responsible for all operational policing in the county.
He was awarded a Queen's Police Medal in the 1999 Queens Birthday Honours.
He had been promoted to chief constable shortly before the Holly and Jessica case.
He faced criticism when it emerged that he had gone on holiday during the hunt for the missing
schoolgirls, while many of his officers were putting in 20-hour days.
He cut the trip short and returned home.
