BELLEFONTE, Pa. >> Police are investigating a tip a missing prosecutor connected to former Pennsylvania State University assistant football coach Jerry Sandusky’s child sex abuse case was killed and dumped in a mine shaft.

Bellefonte police Detective Matthew Rickard says the tip regarding the 2005 disappearance of Centre County District Attorney Ray Gricar (GREE’-kar) is being investigated and the FBI is involved.

Gricar decided not to charge Sandusky in 1998 after a boy’s mother complained to State College police about abuse.

Gricar was declared dead this year at his daughter’s request.

The Altoona Mirror newspaper (http://bit.ly/18fGGBn) reported today that Gricar’s nephew says he takes the new claim with a grain of salt because there have been so many false leads over the years.

Sandusky was convicted last year of child sexual abuse but says he’s innocent.
