Final Madoff defendant sentenced to six months in prison

Irwin Lipkin, one of Bernard Madoff's longest-serving employees, was sentenced to six months in prison on Wednesday for falsifying records that helped the imprisoned fraudster carry out his multibillion-dollar Ponzi scheme.

The sentencing marks the end of the criminal case in the wake of the fraud scheme. It comes over six years after Madoff's arrest, according to Reuters.

Lipkin, 77, was the last of 15 defendants to be sentenced. He worked as the Madoff firm's controller.

Madoff is serving a 150-year prison term after pleading guilty in 2009 to leading a scheme to defraud investors by as much as $17 billion.
