And after more than ten years as a deputy coroner and then as its chief coroner, Louis Cataldie has seen his fair share of unusual and disturbing cases. They range from the bizarre to the heartbreaking: an LSU professor killed by a barn door; the bones of a young woman found scattered in a churchyard; and as many as three serial killers loose at one time under Cataldie's watch. He has worked the scene of one of the Malvo/ Muhammad Beltway Sniper shootings and had a hand in bringing to justice serial killer Derrick Todd Lee in a controversial investigation that was featured in an ABC Prime Time special with Diane Sawyer and Patricia Cornwell.
