LOCKPORT – A Niagara Falls man, charged with selling cocaine to a police informant on his street July 24, pleaded guilty Tuesday in Niagara County Court.

Carl A. Zimmerman, 34, of Pierce Avenue, admitted to third-degree criminal sale of a controlled substance and was admitted to the judicial diversion program of court-supervised drug treatment by County Judge Matthew J. Murphy III.

If Zimmerman, a second-time drug felon, fails in the program, he faces as long as 12 years in prison.

Successful treatment would reduce the charge to a misdemeanor with a probation sentence.
