Jackson Police are mourning one of their own. On their facebook page they said “It is with great sorrow we announce the passing of retired K-9 Stryker. Stryker proudly served the citizens of Jackson from 2007 to his retirement September of 2015. Last week it was learned that Stryker had developed cancer and had to be put down due to the pain and suffering. Stryker made one last visit to The Jackson Police Department Monday as officers and staff said their goodbyes.
