Battle Ground — While on a tour of the Battle Ground Police Station, Cub Scouts of Den 1, Pack 443 walked into one room to find an overturned chair, a patch of hair on the floor, a seemingly bloody knife and a drinking glass left on the table. It was a mock crime scene set up by Sgt. Kim Armstrong, who then walked the troop through forensics and the application of science in criminal investigations. The scouts learned about the integrity of a crime scene, evidence collection, the characteristics of fingerprints and DNA and how each can be used to identify suspects and solve crimes. “They asked great questions,” Armstrong said in a release from the city. “I think we have some future scientists and detectives in the group.” Armstrong also took the troop on a tour of the station, visiting the interview rooms, armory, holding cells, evidence processing room, patrol room and Emergency Operations Center.
