When investigators found the body of Ally Kostial, a student at the University of Mississippi in Oxford, in July 2019 near a remote fishing camp not far from campus, they wondered why someone would so brutally take the life of the 21-year-old.
Kostial, originally from St. Louis, Mo., who was studying business and marketing, was shot at least nine times.
48 HOURS and Michelle Miller, co-host of CBS SATURDAY MORNING, investigate the murder of Kostial and the digital trial investigators followed to find her killer, in “What Ally Kostial Didn’t Know,” to be broadcast Saturday, March 5 at 10 p.m. EST (9 p.m. CST) on the CBS Television Network and streamed on Paramount+.
Prosecutors say this case raises questions about missed warning signs in relationships and whether the murder could have been prevented.
Investigators were able to track Kostial’s life before her death through her Apple Watch, which stored text messages, leading Lafayette County sheriff’s deputies to fellow student Brandon Theesfeld. He was arrested three days after Kostial was found and has since pleaded guilty to her murder.
“The hardest thing is to go back and read her messages,” says Lafayette County district attorney Ben Creekmore.
Theesfeld’s attorney Tony Farese calls the case “a tragedy of Shakespearean proportions.”
