Maksim Gelman, the 23-year-old Brooklyn resident accused of killing four people and stabbing four during 28 hours of violence spanning Brooklyn, Queens and Manhattan, was booed outside the 61st Precinct in Sheepshead Bay. A crowd yelled, "Pig!" "Killer!" and "Rot in Hell!" Gelman yelled back, "Shut up, man!" And at the courthouse, Gelman told reporters, "This was a setup, man. This is bulls---."

Gelman was charged with four counts of second-degree murder, single courts of first-degree and second-degree assault, and three counts of first-degree robbery. According to authorities, Gelman's alleged crime spree included: Killing his mother's companion in their apartment early Friday morning in Sheepshead Bay; killing an ex-girlfriend and her mother Friday during the day (he first killed the ex's mother and then waited in her apartment to kill her); stabbing a driver and stealing his car; fatally striking a pedestrian; stabbing a livery cab driver and trying to steal his car at Eastern Parkway and St. Mark's Place; stabbing another driver and stealing his car in Crown Heights; and stabbing a subway passenger on a 3 train at Penn Station before being captured.

The Daily News notes that when Gelman was brought to the holding cells at the courthouse, "The mocking continued in the courthouse holding cells, where fellow prisoners shouted, 'Throw him in here with us!'" Gelman bragged, "You're in here for nickel bags - go look what I'm in here for!"

Gelman is no stranger to law enforcement authorities, but his previous offenses were not violent, with 10 arrests "since 2003, several times for graffiti-writing, but most recently, in January, for possession of crack cocaine," according to the NY Times. A neighbor said, "When I was little he kind of did bully me. He used to take my water guns and put in hot sauce and soap." Lately, Gelman's actions were more intense—the Times reports, "He was behaving so belligerently and menacingly one night last fall at the Blue Velvet Lounge, on Avenue U, that the lounge’s owner said she had to make him leave." Owner Yana Levin said, "You learn to tell the difference between when a person is just talking, and when somebody has aggressive intent... He was saying, ‘Oh, you might regret it. You’ll throw me out now, but you might live to regret it.'"
