In Florida in 2015, Amanda Colley was starting her life over after a contentious divorce and an ongoing custody battle with her ex-husband, James. The 36-year-old mother of two was excited about a new love interest, Lamar Douberly. Then, one summer night, she returned to a ransacked house. Lamar and two girlfriends arrived to join her as police were called. Then, gunshots rang out; glass shattered. After more shots, Amanda and her friend Lindy, a mother of three, were both dead and Rachel was injured. The gunman took off. James Colley was arrested 600 miles away and brought back to Florida to stand trial for double murder, with both Lamar and Rachel giving dramatic firsthand testimony.

When Ohio State senior Reagan Tokes failed to respond to messages from her parents, they feared the worst. Their nightmare became a reality when a 911 caller reported the discovery of a female body in the local park. She had been shot execution style. Knowing a brutal killer was on the loose, detectives raced to solve the crime, gathering surveillance video and photos that tracked Reagan's last moments. Brian Golsby, a previously convicted sex offender, was arrested. Golsby confessed to abducting Tokes, admitting he forced her to withdraw money from ATM accounts, but he adamantly denied killing her, insisting an accomplice he called "TJ" committed the murder. At trial Golsby continued to maintain his innocence; but even his highly regarded defense team couldn't produce TJ.
