LOCKPORT – Donald J. Frey, of Lockport, who has been in a court-supervised drug treatment program for 13 months after admitting to burglary, pleaded guilty to two more crimes Wednesday, including the theft of a credit card that had belonged to a woman who had been fatally stabbed.

Frey, 38, of Lincoln Avenue Extension, admitted to fourth-degree grand larceny and third-degree burglary. Niagara County Judge Sara Sheldon Farkas kept him in the judicial diversion program of court-supervised drug treatment, where he has reportedly been doing well.

The crimes predated his admission to that program. On March 2, 2012, he burglarized his neighbors’ home, stealing $2,400 worth of property, and on April 12, 2012, he took a credit card that had belonged to the late Norma Confer and ran up $677 worth of charges.

Frey’s father is the executor of the estate of Confer, who died May 25, 2011, 34 days after she was stabbed by Hans S. Diefenbach of Lockport.

Diefenbach pleaded guilty to first-degree manslaughter and is serving a 10-year prison sentence.
