The body of Alexandria “Ally” Kostial, a Missouri native who was majoring in marketing, was found Saturday about 10 miles from the Ole Miss campus in Oxford. The 21-year-old senior had last been seen alive Friday night.

Brandon Theesfeld was arrested in connection with her death. He was booked into the Lafayette County Jail Monday, where he is being held without bail.

Theesfeld’s initial court appearance was Tuesday morning. He wore an orange prison jumpsuit and had his hands cuffed in front of him and his ankles shackled as he was led from the courthouse.

Theesfeld was a senior at Ole Miss studying business. A university spokesperson says he has been suspended. He’s now being held in jail without bond.

A mugshot was later released by the Lafayette County Sheriff’s Office.

Although authorities have not revealed how the young woman died, sources told Mississippi television station WLBT-TV that she had been shot eight times. Authorities would only say her death was a result of foul play.

On Facebook, Kostial’s father said his daughter was in Oxford attending summer school and teaching fitness classes.

It is currently unclear how, if at all, Theesfeld and Kostial knew each other.

CBS 11 News learned that Theesfeld attended Country Day School in Fort Worth from 2012 to 2014 but did not graduate from there.
