New York (CNN) -- The man accused of killing four New Yorkers during a violent stabbing spree in February has pleaded guilty to several counts of murder, according to the Kings County, New York, district attorney's office.
Maksim Gelman, 23, was accused of stabbing his stepfather, ex-girlfriend and her mother to death, during a rampage that terrorized three New York City boroughs for roughly 28 hours. Police say he also killed a man with a car and slashed at least five other people before being apprehended by police while trying to break into a subway conductor's cab.
"There's no negotiated plea," Edward Friedman, Gelman's attorney, said Thursday. "The district attorney never made an offer, their position was that they wanted to go to trial."
Gelman pleaded guilty Wednesday to four counts of murder, two counts of attempted murder, three counts of assault and several counts of robbery.
"While it is unusual for a defendant to plead to the top charges against him without promise of benefit the overwhelming evidence in this case left him with little option," District Attorney Charles J. Hynes said in a press release.
Gelman will be sentenced on January 11, 2012.
According to Friedman, Gelman can expect to receive a minimum sentence of 25 years to life.
