DNA Matches

  • Reference Number: 2622
  • Date released: 12 August 2010

Request

I am writing to request the following information:

  • Whether 'cold case' files on sex attacks are being reviewed by the force;
  • If so, how many DNA profiles have been found;
  • Whether those profiles have been loaded onto the DNA database;
  • If so, how many of those have resulted in a positive match;
  • How many sex attackers have been caught and convicted as a result of reviewing cold case files.

Response

In accordance with section 1 (1) (b) of the Act our response is provided below;

'Cold case' sex attacks are under review by the Cheshire Constabulary. There have been a number of apparently sexually motivated murders dating back at least 40 years. There have also been a number of undetected rapes dating back some 8 years. In all of these cases and certainly with the more recent cases, there is a possibility that the offender may be traced.

In respect of that part of your request relating to the obtaining & loading of DNA, I have carefully considered your request and I am not obliged to release the information to you. This letter serves as a Refusal Notice under Section 17 of the Freedom of Information Act 2000 (the Act).

Section 17(1) of the Act provides:

(1) A public authority which, in relation to any request for information, is to any extent relying on a claim that any provision in part II relating to the duty to confirm or deny is relevant to the request or on a claim that information is exempt information must, within the time for complying with section 1(1), give the applicant a notice which-

(a) states the fact,

(b) specifies the exemption in question, and

(c) states (if that would not otherwise be apparent) why the exemption applies.

In accordance with the Act, this letter represents a Refusal Notice for that particular part of your request , the Cheshire Constabulary can neither confirm nor deny that it holds the information you requested as the duty in S1 (1 )(a) of the Freedom of Information Act 2000 does not apply, by virtue of the following exemptions:

Section 30(2) Criminal Investigations

Section 30 (Investigations and proceedings conducted by public authorities) of the Act states

(3) The duty to confirm or deny does not arise in relation to information which is (or if it were held by the public authority would be) exempt information by virtue of subsection (1) or (2).

This is a qualified exemption for which I am required to conduct a public interest test.

Factors favouring confirming or denying that information is held for Section 30

Confirmation or denial that any information exists in relation to the obtaining of evidence would enlighten members of the public as to the success or otherwise of the investigation techniques and the use of certain types of evidence, in this case DNA This may go some way to promoting awareness and accountability where it relates to the efficiency of the Constabulary and in respect of expenditure of public funds.

Factors against confirming or denying that information is held for Section 30

The existence or otherwise of DNA evidence could be, and in many cases certainly is, a critical factor in the investigation process. To confirm that we have obtained such evidence or to confirm that we don't hold such evidence would do nothing to aid the investigation but could inform the offender(s) of the liklehood or otherwise of being caught. For example the rape and murder of a women where no DNA evidence was obtained might make the offender think that there is less likelihood of being traced and may incite further crime.

To release this information may adversely affect public safety if the criminal fraternity are provided with a tactical advantage over the Police. As outlined previously, this information, linked with related subject matter, begins to assist those with illegal intent.

Balance test for neither confirming nor denying that the information exists

Police forces would never disclose information that would put people at risk or compromise law enforcement. By confirming or denying whether the requested information is held in this case would mean that criminal investigations would be less effective and the small benefit in increased public awareness would not be adequate compensation for such an impact on society.

We would draw your attention to Case FS50078588 – Guardian Newspaper v ICO and Avon and Somerset police (Jeremy Thorpe). It was established in this case that the disclosure of information particularly where Sec 30 is engaged, need only be for a tangible community benefit and the public interest is not defined by matters that the public would simply just find interesting.

It is therefore our opinion that the balance lies in favour of neither confirming nor denying that the information exists.

In formulating our response we fully accept that the circumstances will vary considerably with each Police Force. The release of information in relation to an investigation, whether it be DNA success or otherwise, has to be carefully considered and may only be released where there in no likelihood of prejudice to the investigation which is a judgement call for each investigating officer.
