The Putnam County Sheriff Deputy stabbed during a response to a domestic incident Monday has undergone another surgery.  Sheriff Robert Langley says the damage was more extensive than originally thought, but both surgeries went well.  The Deputy was discharged from New York-Presbyterian Hudson Valley Hospital yesterday with a good prognosis for a full recovery.  Members of the Putnam County Sheriff's Department, local law enforcement, K9s and a helicopter fly over from the Westchester County Police stood by.
