Coatesville Area School District officials announced Tuesday that the district's superintendent and an athletics director had resigned - and that they could not comment further because of an investigation by the Chester County District Attorney's Office.

In a brief statement, board officials said Richard Como, the superintendent, and Jim Donato, Coatesville Area High School director of athletics and activities, had submitted letters of resignation. The board is to vote on those letters Sept. 24.

Como initially announced his retirement two weeks ago in a post on the district website.

The board would not comment on the nature of the investigation. District Attorney Thomas Hogan did not immediately return a call for comment.

The district, officials said, is launching an internal, noncriminal investigation.

At Tuesday's committee meeting, parents and teachers said they felt frustrated by what they called a lack of communication from the board.
