Juan Martinez is counted amongst the top death-penalty prosecutors in Arizona. In his twenty-seven-year career with the office, he has spent nineteen years prosecuting homicide cases. He gained prominence as the prosecutor in the Jodi Arias murder trial that captured the nation, which for the first time ever is explored in his book Conviction: The Untold Story of Putting Jodi Arias Behind Bars (William Morrow).
Through two trials, America watched with baited breath as Martinez fought relentlessly to convict Jodi Arias of Murder One for viciously stabbing her ex-boyfriend Travis Alexander to death. Now, speaking openly for the first time, prosecutor Martinez unearths in his book Conviction new details from the investigation that were never revealed at trial, exploring key facts from the case and the pieces of evidence he chose to keep close to the vest. Throughout the trials, his strident and unfaltering prosecution strategy was both commended and criticized, and in his book, Martinez illuminates the unique tactics he utilized in this case and how they lead to a successful conviction. Going beyond the news reports, Martinez explores the truth behind the multiple facades of Jodi Arias. Sparring with her from across the stand, Martinez came to know Arias like no one else could, dissecting what it took for a seemingly normal girl to become a deluded, cunning, and unrepentant murderer.
Some of his most noteworthy cases include Arizona v. Wendi Andriano, who was convicted of first-degree murder and was the first woman sentenced to death by a jury in Arizona; Arizona v. Scott Falater, which was noted for the use of sleepwalking as a defense to the murder of his wife; Arizona v. Loren Wade, in which an Arizona State University football player was convicted of the shooting murder of an ex-ASU football player; and Arizona v. Rick Wayne Valentini, which resulted in a conviction for murder even though the victim’s body was never found.
Martinez was admitted to the bar in 1984. He is a Maricopa County prosecutor, where he began working in 1988. Today he resides in Arizona.
