OK Carana. Have you ever come across a case where "dozens have been arrested" or "hundreds questioned under caution"? in a missing child investigation? (Or any other)
People may not have been "arrested in their dozens" or "hundreds questioned under caution" as far as we know, in the Valerie Graves murder inquiry, but the police certainly pulled out all the stops in an attempt to apprehend the perpetrator.

Police are calling on all men in a Sussex village to submit themselves for mass DNA tests in the hunt to find the killer of a grandmother.
All men over 17 in Bosham, West Sussex, have been asked to take the test to help crack the unsolved murder of Valerie Graves, who was killed with a claw hammer as she house-sat for friends last year.

As the hunt steps up, all men who live, work or visit the Bosham area have been called on to eliminate themselves from suspicion by agreeing to provide a mouth swab and thumbprint.

More than 9,500 people have been interviewed by police - more than twice as many as live in Bosham which has a population of around 4,000 in the 2011 census.
