Authorities have filed charges against three more people in the case of a Pennsylvania 911 operator accused of failing to send an ambulance to the rural home of a woman who died of internal bleeding about a day later.

According to a criminal complaint, the three men were charged Monday with tampering with public records, tampering with or fabricating evidence and obstruction.

They are or were managers for Greene County’s emergency management. Prosecutors allege they failed to provide policy memo binders that detail standard operating procedures.
