(CNN) A Texas man is charged with murder after the body of a 21-year-old University of Mississippi student was found near Oxford over the weekend.

On Tuesday, the Lafayette County Sheriff's Department and the Mississippi Bureau of Investigation arrested and charged Brandon Theesfeld with the killing of Ally Kostial, the sheriff's office told CNN.

Citing the ongoing investigation, the sheriff's office declined to release more details.

"We want to thank the family of Alexandria for their patience and their trust," the department said.

Theesfeld attended the same business administration school at Ole Miss as Kostial, said university spokesman Rod Guajardo, who added that Theesfeld is now suspended. Prior to Ole Miss, Theesfeld attended but did not graduate from Fort Worth County Day, a private, non-denominational school, for two years ending in 2014.
