WILKES-BARRE, Pa. (AP) --Three former Pennsylvania police officers accused of covering up the beating death of an illegal Mexican immigrant have been acquitted of the most serious charge against them. A federal jury found former Shenandoah Police Chief Matthew Nestor and subordinates William Moyer and Jason Hayes not guilty of conspiracy to obstruct a federal investigation. Moyer faced five counts. He was found guilty Thursday of lying to the FBI. Nestor was found guilty of falsifying police reports. Hayes was acquitted of both charges against him. The three had been accused of helping a group of white high school football players cover up their roles in the July 2008 attack on 25-year-old Luis Ramirez. Two men were convicted of a federal hate crime for beating and kicking Ramirez.
