A lawyer for a former pediatrician serving a life sentence for sexually abusing scores of young patients appealed Wednesday to the Delaware Supreme Court, arguing that a search warrant didn't allow police to seize a flash drive containing videotaped sex crimes against children.

Earl Bradley, 59, was sentenced last year to 14 life sentences without parole for 14 counts of first-degree rape. He also was sentenced to more than 160 years in prison for multiple counts of assault and sexual exploitation of a child in a case that shook this small state.

Bradley was convicted by a judge who viewed more than 13 hours of videos showing sex crimes against more than 80 victims, most of them toddlers. The videos were seized by police who executed a search warrant in 2009 at his Lewes office complex, which was decorated with Disney themes and miniature amusement park rides.

Bradley had waived his right to a jury trial after the trial judge denied a defense motion to suppress the video evidence because it had been illegally seized.

Defense attorneys argued Wednesday that Bradley's convictions should be reversed because the warrant did not allow police to search an outbuilding in which a computer flash drive containing the videos was found. They also said the warrant didn't allow authorities to seize the flash drive.
