Chad Ryan DeSoto Convicted of Guam Crash and Stabbing Rampage

HAGATNA, Guam -- A jury convicted a Guam man Monday of murdering three Japanese tourists in a crash and stabbing rampage last year that hurt 11 others. The panel of 10 women and two men rejected the mental illness defense of 22-year-old Chad Ryan DeSoto. His lawyers argued he spiraled out of control into psychosis after his grandfather died and his girlfriend moved to Utah.

The jury agreed with prosecutors who say DeSoto knew what he was doing during the attack in a busy tourist spot on Feb. 12, 2013. DeSoto was accused of barreling his car down a busy sidewalk, crashing it into a convenience store and getting out and stabbing people who were nearby. DeSoto was also convicted of attempted murder. He faces life in prison without the possibility of parole when he is sentenced Sept. 25. "Justice has been done for the families of the victims," Chief Prosecutor Phillip Tydingco said. The rampage rocked the small island U.S. territory. Guam's economy depends heavily on tourism. Prosecutors argued DeSoto planned the attack, targeting victims who resembled or symbolized his girlfriend, who had recently dumped him.
