OXFORD, Miss. (AP) — Police have arrested a University of Mississippi student from Texas, saying he killed a female Ole Miss student from St. Louis..

Lafayette County Sheriff’s Major Alan Wilburn says 22-year-old Brandon A. Theesfeld is charged with murder in the death of Alexandria “Ally” Kostial.

A 21-year-old from St. Louis, Kostial was found dead Saturday night in the Harmontown community near Sardis Lake, about 30 miles (50 kilometers) from campus.

Theesfeld was arrested Monday afternoon and booked into Lafayette County jail. He appeared before a judge Tuesday, but bail will be decided later.
