The Iowa Department of Public Safety says a 4-year-old female Labrador retriever trained in explosive detection has joined the agency.
The dog named Casey arrived in Iowa on Friday from North Carolina. Iowa was able to adopt her for free under a program overseen by the Marine Corps that makes dogs available after their return from overseas military deployments.
State Fire Marshal Ray Reynolds says the dog completed a seven-month tour in Afghanistan, where she saved "multiple soldiers' lives" due to her skill at sniffing out improvised explosive devices.
Casey will join two other dogs used by the State Fire Marshal Division.
A yellow lab named Rocket detects flammable liquids and Kodi, a Belgian Malinois, detects explosives.
