A Los Angeles Superior Court judge found a Florida man guilty Friday of stalking Olympic gold medal gymnast and Dancing With the Stars champ Shawn Johnson. The judge determined that the man, 36-year-old Robert O’Ryan, was legally insane at the time of his arrest last March. O’Ryan was found guilty of felony stalking and burglary charges as well as two misdemeanor concealed-weapon violations. He was arrested after he jumped a fence at CBS Studios in Los Angeles, where Dancing With the Stars was being filmed. Police found two loaded guns in the man’s car, along with duct tape and love letters to the Olympian.
