UPDATE 7:08 PM -- NOW SECOND NYPD COP "MISSING" ALSO INVOLVED IN LAPTOP CASE . . . .

A high-ranking New York City Police Department officer has died from an allegedly self-inflicted gunshot wound to the head. Deputy Chief Steven Silks was found in an unmarked patrol car wearing civilian clothes Wednesday evening, just one month before he would turn 63 and face mandatory retirement.

He allegedly shot himself in the head, with the gun reportedly discovered beside him.

He was very closely and heavily involved in the investigation of the Laptop seized from former Congressman Anthony Weiner which allegedly held volumes of Hillary Clinton email evidence on it.
