(Saint John)-The Saint John police force say in an affidavit that the release of search warrants in the Richard Oland homicide Investigation could jeopardize their work.

 The affidavit was released today after a hearing was held in provincial court to determine whether the search warrants should be made public.

In the affidavit, Const. Stephen Davidson says he’s concerned that releasing some details contained in the search warrants could weaken investigative techniques and possibly identify some of the people interviewed by police.

 Davidson, who is  the lead investigator in the Oland case, says 378 exhibits have been seized and 243 of them require forensic analysis  adding that some items still need to be sent for analysis more than a year after Oland’s death.

Police have concluded that Oland’s  death was a homicide, but they have not said how he was killed.
