GRAND JUNCTION, Colo. — A Colorado man who was sentenced to more than 300 years in prison for sexually assaulting six children was released after an appeals court determined that his right to a speedy trial had been violated.

The Grand Junction Daily Sentinel reports 46-year-old Michael McFadden was released from prison Tuesday after the Colorado Supreme Court declined to hear the case.

McFadden was convicted in 2015, but his trial was delayed after his attorneys sought to include provisions in the juror questionnaire and the judge granted a continuance. Colorado’s appellate court ruled that the delay couldn’t be attributed to McFadden, who won’t have to register as a sex offender because his convictions were vacated.

District Attorney Dan Rubinstein says he’s appalled by the decision, but “we are without remedy.”
