MOUNTAINBURG, AR - Authorities in this northwest Arkansas town have apprehended a man whose pregnant wife was found slain last week.
After a six-mile chase on Interstate 540 through Crawford County, police arrested 30-year-old William Stewart and 32-year-old Albert Johnson Thursday afternoon.
The pair was in a gold Malibu with a fraudulent license tag, and both men have felony warrants on weapons charges out of Missouri.
Kansas City police call Stewart a "person of interest" in the death of his pregnant wife, 21-year-old Ashley M. Tyler-Stewart and another woman, 19-year-old Alisa R. Winrow. No charges have been filed against Stewart or Johnson in connection with the deaths.
Tyler-Stewart, who was seven months pregnant, and Winrow were killed August 17 when someone fired 10 to 15 shots into their parked car on a midtown Kansas City street. Relatives said that Tyler-Stewart's son died 45 minutes after being delivered after the shooting.
Police described the killings as drug-related.
