Vincennes Police K9 officer Sgt. Mike Caswell and his family are mourning the loss of his K9 partner.

It’s believed the police dog, Gary, suffered a seizure as he was unresponsive when Sgt. Caswell reported for duty Wednesday to utilize K9 to assist in a search warrant.

The Vincennes Police Department says the dog was rushed to the vet and stabilized and prepped for transport to Purdue.

Shortly after, Gary suffered another episode and the decision was made to end his suffering and put him down.

The Vincennes Police Department asks the public to remember Caswell and his family as they deal with the unexpected loss.
