The Washington State Patrol K9 Memorial was unveiled on August 15, 2017. It is located at the Washington State Patrol Academy.
On April 14, 2016, Trooper Mike Allan (Homeland Security Division/ #817) and his K9 partner Patrick, X-164, participated in explosive detection training at the AMTRAK Seattle Sounder station, and returned to the Coleman Ferry Terminal where Patrick screened two Ferry loads of cars for explosives. After conducting his work and while travelling home, Trooper Allan saw Patrick was in distress. Trooper Allan rushed Patrick to a vet and emergency surgery was conducted to try and save Patrick who was suffering from tangled intestines. The surgery was not successful.
Patrick was a three-year-old German Shepherd and was a Transportation Security Administration supported K9. Trooper Allan and Patrick started their career together at Lackland Airforce Base in Texas in October 2015. On December 10, 2015, Patrick and Trooper Allan became a certified K-9 explosive team and served the citizens of Washington faithfully.
