“We are profoundly fortunate to the members of our community that reached out to us with information,” said Police Chief Mary Gavin. “Stepping forward isn’t always easy, or people may think they don’t have important details – but you never know where that may lead. We appreciate the support of our Community. We are also grateful to the Metro Transit Police for their arrest of the individual. The multi-jurisdiction partnerships we have in the region are unmatched and critical to successfully doing our job.”
