Did social media cause an Olympic horseman to shoot his own student?

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 in "The Shooting of Lauren Kanarek," the 35th season premiere of "48 Hours" airing Saturday, September 17, at 10/9c on CBS and streaming on Paramount+.

It was as great a fall from grace as his elite equestrian sport had ever seen. Barisone excelled at dressage — training horses to seemingly dance. He was considered one of the best coaches in the world, teaching fellow Olympians like Boyd Martin and Allison Brock, and representing Team USA in Beijing.
