WEST MIFFLIN — A district superintendent has been charged with drunken driving.

State police charged West Mifflin Superintendent Daniel Castagna with speeding, careless driving, drunken driving and other charges stemming from a Beaver County traffic stop about 3 a.m. Sept. 22.

Castagna isn’t commenting because he’s yet to receive the police complaint in the mail.

Parents in the district were upset to learn of the charges Thursday, a day after Castagna announced that an unnamed assistant coach has been placed on leave while the district investigates alleged “inappropriate behavior” with a former student.

Outraged parents packed a school board meeting Thursday night demanding answers about both sets of allegations, but were told both are confidential personnel matters unless and until criminal charges are resolved.
