University of Mississippi student Alexandria Kostial, 21, found dead in apparent homicide, suspect in custody

A Texas man is in custody after police found missing University of Mississippi student Alexandria "Ally" Kostial dead by a remote lake in an apparent homicide.

Brandon Theesfeld, 22, of Fort Worth, was charged with murder Monday after the remains of 21-year-old Kostial were discovered Saturday morning by a Lafayette County deputy on routine patrol near Sardis Lake in Harmontown, Miss., about 20 miles from the university's Oxford campus.

A police source told WLBT that Kostial had been shot multiple times.

Rod Guajardo, associate director of strategic communications at Ole Miss, where Kostial was working to obtain a bachelor's degree in marketing, told the station Theesfeld was enrolled as a student at the School of Business Administration and was suspended following his arrest.

Kostial, a Missouri native and member of Alpha Phi sorority, was taking summer courses and teaching fitness classes at the university when she was killed, according to her family. She was set to graduate next spring.

The victim was last spotted on surveillance footage Friday night stopping at the door of an Oxford Square bar but turning around and leaving before entering the establishment, WLBT reports.

Kostial's roommates told police she returned home around midnight but eventually left again, adding that they did not hear her exit.

It remains unclear where she died or how her body got to Buford's Ridge, a remote area of Sardis Lake with a fishing camp that draws both locals and college students on weekends when the water level is low to hang out or ride ATVs on the lake's bottom.

“It's just shocking," Anna Pasco, a friend of Kostial's, told WMC-TV. "She quite possibly was the nicest human being that I’ve ever met. It's just hard for me because all I can think about when I see her face is what she went through, what she was thinking, what she was saying. It's hard."

"She is a beautiful, beautiful person inside and out and I love her and I'm going to miss her forever," she added.

Theesfeld was expected to appear before a Circuit Court judge on Tuesday.
