He was born in rural Missouri, and it was immediately clear that he was different from the rest. He caught his first criminal when he was just two years old. By his sixth birthday, he had located burglars, rapists, drug dealers, missing children, and murderers—including Utah’s most wanted criminal. Known to friends as JJ, to law enforcement as Michael Serio’s partner, and by captured criminals as “that damned dog,” Jessie Jr. was an exceptionally talented bloodhound, baying like a sea lion that had swallowed a fog horn. Before JJ, few police departments in the West used bloodhounds, and none in Utah. But just when JJ finally convinced naysayers, he and Officer Serio ran into something worse than resistance: the despair of failure amid high hope. JJ had been tracking Brian David Mitchell, the man who abducted Elizabeth Smart, when he was pulled off the track. Elizabeth later told investigators that on the day she was kidnapped she heard a dog baying in the woods behind her.
