NYC Killer Scheduled for Sentencing in Rampage A man who acknowledged killing four people in a rampage of stabbings, carjackings and other crimes is scheduled to be sentenced. Maksim Gelman pleaded guilty to murder, assault and attempted murder in the February 2011 rampage that spanned two days. He pleaded guilty on Tuesday to his final crime, slashing a subway passenger in Manhattan. The other crimes took place in Brooklyn, where he was scheduled to be sentenced Wednesday. Gelman initially said he was not guilty but changed his plea because he said he wanted to start serving time. His lawyer has described his mental state as "fragile." Brooklyn state Supreme Court judge Vincent Del Giudice warned Gelman he's facing up to 100 years in prison. The rampage started during an argument over using the family car.
