UPDATE: A Walker County Deputy has resigned.

Channel 3 reported in July that Deputy Corey Griffin had shot and killed his K-9 partner Rocky, claiming the dog was attacking him.

Sheriff Wilson says the former deputy's resignation was about a domestic dispute back in August and not related to the K-9's death.

Sheriff Wilson says Griffin's actions didn't represent the department in the right way.

"Anything they do on duty and off duty. So we expect them to always uphold an image that is respectable in the community and always carrying the name in a positive light,” Sheriff Wilson said.

Sheriff Wilson says Griffin showed up to a girlfriend’s house drunk.

The incident report says she was watching TV with a friend when Griffin made his way inside started cussing at them.

She told officers nothing physical happened between them, but he needed to leave.

"However, there was some damage done to a door at the residence and that brought the charge of criminal trespass,” Sheriff Wilson said.

The report also states Griffin had been harassing the woman through phone calls and texts.

Sheriff Wilson said they were in a on again off again relationship prior to the incident.

Lafayette police gave Griffin a ride home and the department pressed charges in September.

Sheriff Wilson strongly stated this had nothing to do with K-9 incident in July and believes Griffin’s resignation was the best outcome for everyone involved.

"We addressed it. We investigated it. And determined that the conduct was unbecoming and the fact that he was facing a misdemeanor criminal charge also factored in to the finality of the employment,” Sheriff Wilson said.

Griffin's court date hasn't been set yet.

ORIGINAL STORY: A Walker County deputy is off the job, following his arrest in September in connection to an incident in August.

Deputy Corey Griffin, who shot and killed his K-9 partner back in July, has resigned.

According to an incident report, Griffin was arrested for criminal trespass in connection to an incident in August at a home in LaFayette.

The report says Griffin forced his way into a woman's home and damaged the door.

According to the report, a sergeant who responded to the home said he would give Griffin "a courtesy ride back to his home."

Walker County Sheriff Steve Wilson says Griffin turned himself in on September 24.

Sheriff Wilson says Griffin’s resignation is related to the criminal trespass incident and not the death of his K-9 partner Rocky.

Griffin said he was forced to shoot Rocky, when he attacked Griffin during an arrest in Chickamauga.
