LADYSMITH, Wis. (AP) — Authorities have a suspect in custody in the fatal shooting of a western Wisconsin sheriff's deputy.

Rusk County Sheriff Jeff Wallace says the man surrendered Sunday. Formal charges are pending against the suspect.  He has been identified as 43-year-old Doug Nitek.

Authorities have identified the deputy killed Saturday evening near Ladysmith as 33-year-old Deputy Dan Glaze. Officials had said the deputy was shot while looking into a suspicious vehicle.

Wallace says Glaze had served for 1 1/2 years at the Rusk County Sheriff's Department. Hayward police Chief Joel Clapero says Glaze previously worked at that department from 2007 into 2015.

Wallace says the deputy responded to a call about a suspicious vehicle and told dispatch that it was in a field. Dispatch lost contact, and when backup arrived a short time later, the deputy had been fatally shot.
