Pennsylvania prosecutors are dismissing as unreliable allegations that two assistant coaches at Penn State witnessed Jerry Sandusky having inappropriate or sexual contact with children in the late 1980s.

Solicitor General Bruce Castor says investigators found the reports to be third- and fourth-hand and weren't valuable to prosecutors.

A Philadelphia judge's ruling last week in a lawsuit by Penn State against an insurance company made public the insurer's claim an unnamed assistant coach saw "inappropriate contact" between Sandusky and a child in a school facility in 1987.

The order says another unidentified coach saw "sexual contact" between Sandusky and a child in 1988.

Through his lawyer, Sandusky has denied the allegations.

Sandusky was convicted in 2012 of 45 counts of child sex abuse and is serving a lengthy prison sentence.
