Shawn JohnsonA man accused of stalking 'Dancing With the Stars' winner and Olympic gold medalist Shawn Johnson is guilty, reports.

A judge found Robert O'Ryan guilty of felony stalking and burglary, along with two misdemeanor concealed weapons charges. He also ruled that O'Ryan was legally insane at the time of his arrest.

Police arrested O'Ryan when he jumped the fence at the CBS Studios in Los Angeles while Johnson was filming 'Dancing.' They later found two loaded guns in his car, as well as love letters to the gymnast.

A court-ordered evaluation will determine where O'Ryan serves his sentence, which could be in a state-mental hospital.
