Maksim Gelman, NYC Spree Killer, Due In Court In Subway Slashing

NEW YORK -- A New York City man who has admitted killing four people in a rampage of stabbings, carjackings and other crimes is due in court for an update on a lingering case: a subway slashing that authorities say came at the end of his violent spree last February.

Maksim Gelman has a court date Tuesday in Manhattan. It concerns only a subway attack moments before his dramatic arrest beneath Times Square. A passenger was wounded.

Gelman pleaded guilty in December to murder and other charges in the other attacks. Those killed included his stepfather and a woman whose friends have said Gelman was obsessed with her.

In a shocking interview with the New York Post, Gelman claimed to have murdered six other people as a member of a Brighton beach coke ring. He also expressed no remorse over any of his confessed crimes.

“After you kill one person, it gets easier,” said Gelman, 24, claiming that he ran over his first two victims when he was 18 and driving in southern Brooklyn.

Gelman is to be sentenced Wednesday for those crimes. They happened in Brooklyn. The subway stabbing is a separate case because it happened in Manhattan.
