A Nesquehoning man who robbed a Redner's market clerk almost a year ago will serve 9-24 months in state prison.

Carbon County Court Judge Joseph J. Matika on Friday sentenced Keith Michael Pierce, 48, to the time, to be served after he completes a 3 1/2 to 7-year sentence he's serving in York County on similar charges.

Matika also sentenced Pierce to a year's probation, to be served at the same time, for accepting money to do roof repairs in 2011, but not doing the work. He must return the $506 in that case.

Pierce, who pleaded guilty to robbery and theft on Oct. 11, told Matika his actions stemmed from a crack cocaine addiction which he developed after the loss of his wife in 2010.

Pierce's lawyer, Joseph Perilli, said that before the addiction, Pierce had led a law-abiding life.

According to court documents, Pierce threatened the Redner's clerk with a knife at 6:06 p.m. Jan. 31, robbing her till of $380.

Pierce was caught on video as he held the Redner's clerk at knifepoint, then reached into the cash register to grab the money. He fled, dropping the cash, and stopping to pick up the bills. he left a $5 bill behind.

He was identified by a Redner's representative, who had seen him in the store several times. Police later recovered the knife at Pierce's home.

Pierce appeared in court Friday in prison garb and shackled. He was brought to his sentencing from another state prison, where he is serving 3-and-a-half to seven years for robbing a Hess Express and a Rite Aid drugstore in York county in March.
