BOZEMAN, Mont. (AP) — Authorities have arrested a man suspected of shooting his estranged wife to death in southern Montana.

The Bozeman Daily Chronicle reports 47-year-old Joseph DeWise was arrested Thursday on a charge of deliberate homicide stemming from the death of 35-year-old Lauren DeWise. He is being held in the Gallatin County jail on $1 million bail.

Sunday morning's shooting in Belgrade also critically injured one of Lauren DeWise's roommates, 32-year-old Ashley Van Hemert.

Investigators say another roommate who reported the shooting told them Lauren DeWise had recently moved in and had asked Joseph DeWise for a divorce.

Booking documents do not indicate if Joseph DeWise has hired an attorney.

Investigators say he has repeatedly denied any involvement in the shooting.
