48 Hours - Season 35

Earlier this year, 58-year-old former Olympic equestrian Michael Barisone stood trial in a Morristown, New Jersey, courtroom for the attempted murder of his own riding student, Lauren Kanarek. Barisone's legal team of Ed Bilinkas and Christopher Deininger would gamble on an unusual defense. They claimed that at the time of the shooting Barisone was insane, and not legally responsible for his actions. Insanity pleas are uncommon and rarely successful. Barisone's defense would be that Lauren Kanarek had driven him over the edge, in large part by her use of social media.

Michael Barisone speaks out in his first television interview since the end of his trial.

On Sept. 4, 1981, Jeff and Tim Slaten were awakened by Lakeland, Fla., police and told that their mother, Linda Slaten, had been murdered. Jeff was 15 and Tim was 12. Investigators collected a rape kit and lifted a palm print from the windowsill where the killer had entered. They questioned a slew of suspects, but no one was charged. The case went cold. Prior to and after Linda Slaten's murder, Tim Slaten's football coach, Joe Mills, would regularly drive Slaten to and from football practice. Coach Joe became a role model for Slaten, who proudly hung up his football team photo in his room where Coach Joe stood right behind him. But nearly 40 years later, advances in DNA technology and a carefully stored rape kit revealed Linda Slaten's likely killer: Coach Joe. 48 HOURS and contributor Jim Axelrod report on how detectives and a DNA genealogist finally were able to catch Joe Mills.

On Oct. 10, 2019, Joseph Elledge, then 23, reported his wife, Mengqi Ji, missing.

But when police searched the couple's apartment, they found a muddy pair of Elledge's boots - evidence that would become important months later, after Ji's remains were found buried under a juniper tree. Elledge's boots were found to have several juniper tree needles stuck to the soles. 48 HOURS correspondent Peter Van Sant reports on how DNA from those needles was linked to the tree directly above Ji's shallow grave, providing prosecutors with the evidence they needed to help convict Elledge of her murder.
