Chief Constable Matt Baggott said it was a personal tragedy for her family and the entire police service who would "ensure that no stone remains unturned as we work to bring to justice those who perpetrated this crime".
Garda Commissioner Martin Callinan extended his condolences to the Reynolds family.
First Minister Peter Robinson and Deputy First Minister Martin McGuinness described Constable Reynolds's death as "devastating news".
