TCHULA (AP) — Authorities say a 60-year-old woman was shot and killed while walking with friends.

News outlets report Mary Robinson, who also went by Mary Anderson, was fatally shot while walking with two friends Wednesday morning in Tchula. The woman was struck in the thigh and died at a hospital. Authorities were told that someone opened fire after walking out of a home and 10 large caliber shell casings were found in the area. Robinson was not the target of the shooting.

Holmes County Sheriff Willie March says deputies have brought in a 27-year-old male suspect, who lived in a mobile home in the area and has denied guilt.

Investigators are looking for at least two other potential suspects who lived at the mobile home. No arrests have been made.
