YANKTON, S.D. -

The Yankton County State's Attorney's Office is determining whether criminal charges are warranted in a dog attack that injured a Yankton woman and threatened a sheriff's deputy.

Tonnya Juhnke says she was bitten on her left arm and her legs while trying to protect her own dog from two pit bulls that had gotten loose from a neighbor's yard on Sept. 25.

She went to a hospital emergency room for treatment that included 23 stitches on her arm. Her dachshund was killed.

Sheriff Jim Vlahakis says a deputy who responded to the scene also was charged by the dogs, and the officer shot and killed both of them. The investigation has now been turned over to county prosecutors for review.
