SIOUX CITY, Iowa (AP) – The grieving family of an officer has bought his police dog from the Sioux City Police Department. The Sioux City Journal reports that Sgt. Jay Fleckenstein died Friday of natural causes at his home. He was 39.

The department bought the dog, a Belgian Malinois named “Eik,” from Fleckenstein in 2009. The officer had raised and trained Eik since he was a puppy. A police news release says the purchase agreement included an option that Fleckenstein’s family would be able to buy back Eik if Fleckenstein were to leave the department for any reason.

Eik had nearly six years on duty with Fleckenstein. The dog would have been required to be recertified before returning to service with another officer.
