Four Labor Department employes, including a payroll department supervisor, have entered guilty pleas here in connection with a fraud scheme in which they generated and cashed about $13,000 in payroll checks to which they were not entitled.

The supervisor who pleaded guilty yesterday before U.S. District Judge June L. Green was Jeffrey L. Benton, 31, of 7800 Muncy Rd., Landover. He could be sentenced later to a maximum of five years in prison for his plea to one charge of filing false claims for government money.

According to Assistant U.S. Attorney Judith Hetherton of the fraud division, Benton worked in the section of the payroll department of Labor that generated checks for employes who had lost theirs, or for new employes whose checks were not yet handled routinely.

Between March and November of last year, Hetherton said, Benton would have checks made out in his name and the names of others. Then, the prosecutor said, Benton would enter notations on various work sheets and computer forms that the checks were being issued properly to employes who had already been paid.

Benton received almost $10,000 worth of checks himself and caused more than $3,000 in checks to be issued to the other three participants, Hetherton said.

On Tuesday, another Labor Department employe, Mildred D. Lipscomb, of 6832 Forest Ter., Landover, pleaded guilty before Judge Greene to one count of false pretenses in connection with her receipt of about $2,000 worth of the checks. She is a payroll clerk, and could be sentenced to a maximum of 1 to 3 years in prison.

Guilty pleas were entered earlier to misdemeanor charges by Shirley Hines, of 1414 South View Dr., Oxon Hill, and Ann Wyder, of 325 P St. NW.
