BELLEFONTE, Pa. (AP) — Former Penn State assistant football coach Jerry Sandusky asked a judge on Thursday to overturn his child sexual abuse convictions and grant him a new trial, claiming his lawyers lacked sufficient time to prepare and the statute of limitations for some charges had expired.

Sandusky’s lawyers made the filing at the courthouse in Bellefonte where he was sentenced two weeks ago to 30 to 60 years in prison after being convicted of abusing 10 boys, some on Penn State’s campus in State College.
