(Waterloo Regional Police) Former Waterloo Regional Police Sgt. Caleb Roy has been found not guilty of sexual assault of a woman in October, 2010. The woman's identity has been protected by a publication ban. "Cases such as these where two people give two opposing versions of an event are the most difficult cases for a trial judge to assess," Justice Katherine Corrick told a virtual courtroom Friday.
