Did clues from an Apple Watch solve a college student's murder?

When Cindy Kostial chatted with her daughter on the phone the evening of July 19, 2019, she had no idea it would be the last time she'd hear Ally's voice. Cindy says she and her husband Keith had visited Ally in Oxford, Mississippi, earlier that week. "She wanted us to stay an extra day, she was having so much fun. She wanted me to cook her home cooked meals." 

Ally Kostial, who'd just finished her junior year at Ole Miss, was excited to have her parents visiting from St. Louis, Missouri, as she decorated her campus apartment, according to Cindy. "We went shopping. She loves a beach theme, so we just bought a bunch of new décor."

Now back home, Cindy talked to Ally around 7 p.m. on that fateful Friday night. "She had just woken up from a nap. I said, 'What are you going to do tonight?' She said, 'I'm going to go out with some friends.' So, I didn't worry about it because I know she does that all the time. And I said 'Oh, that should be fun.'"
