CORPUS CHRISTI, Texas—Investigators in Wyoming have arrested the brother-in-law of a South Texas woman found shot to death in her house.

Laramie County, Wyo., jail records show Tommy Caughman (KAHF'-muhn) was being held Thursday for officers in Texas. Nueces (nyoo-AY'-sis) County Sheriff Jim Kaelin says Caughman was arrested Wednesday in Cheyenne, Wyo., and faces a murder charge.

Jail officials had no record of an attorney for the suspect accused in the slaying of Elizabeth Caughman of Bishop, near Corpus Christi. Her body was discovered Jan. 15 at the family's home.

Authorities say Tommy Caughman, who's the brother of the victim's husband, had lived with the couple and their two children.

The suspect had the family's truck when he was initially arrested on theft and unauthorized use of a motor vehicle charges.
