A Gillette man was arrested Tuesday for allegedly killing his wife at the couple's home.

The Campbell County Sheriff's Office say a 10-year-old girl called 911 at about 12:45 p.m. Tuesday, saying her father was hitting her mother.

The girl had reportedly left the residence at 1573 Midland Road, and was calling from a cell phone.

Deputies arrived and made sure the girl was safe before entering the home.

Authorities found 46-year-old Timothy Welch inside the residence. Also inside, and pronounced dead at the scene, was 41-year-old Kayleen Welch.

The Sheriff's Office says the on-scene investigation led deputies to believe that Timothy Welch was responsible for the death of Kayleen Welch.

Timothy Welch was arrested. Charges are being pursued through the Campbell County Attorney's Office.

A cause of death has not been released.
