(Peter Blanchard/Patch) DOYLESTOWN, PA — A former top prosecutor in the Bucks County District Attorney's Office who was demoted last month has filed for resignation. The departure of Assistant District Attorney Gregg Shore will become effective Wednesday, a DA's spokesperson confirmed. Once the second-in-command in the district attorney's office, the longtime prosecutor's resignation comes less than a month after news of his side job as a DoorDash delivery driver — at times during normal work hours — became public. Subscribe Bucks County District Attorney Matt Weintraub had said that Shore had exercised poor judgment but decided not to fire him in part due to past performance, perhaps most notably as the lead prosecutor in the Cosmo DiNardo and Sean Kratz 2017 murder trial.
