Cook, a high school health teacher, reportedly drew her ex-husband Travis Cook outside his apartment by messaging him that she'd be dropping off cold medicine for the former couple's 3-year-old twins. When Travis Cook walked to the parking lot, Chelsea snuck into the home and refused to leave. When her ex-husband returned inside, she locked herself in the bathroom while he called 911. Then, less than a minute later, she suddenly walked out, grabbed a gun from her coat and fired the fatal shots.

Williams’ family told the Associated Press that Cook had harassed the 26-year-old woman online, on the phone and in person for months before the shooting. They said the harassment started in June and included confrontations at the bank where Williams worked as a teller, bullying on Instagram and phone calls made from the high school where Cook worked. “I worried for her safety every day,” said Williams' mother, Tawny Williams
