The man suspected of carrying out a terrifying stabbing spree, spoke to the press Tuesday from the prison mental facility at Bellevue Hospital.

Appearing extremely agitated, Makism Gelman told the New York Post, "Sometimes, my mind isn't right."  

When asked directly if he had killed Yelena and Anna Bulchenko, Gelman reportedly said, "The proof is in the pudding. I'm trying to make my peace with God!"

Gelman's body language revealed his inner turmoil -- he was reportedly rubbing his unshackled hands nervously, his eyes darting back and forth without making contact, jerking upright and then slumping in his chair.

Towards the end of the interview, Gelman descended into paranoid conspiracy theories.

"The DEA set me up. They were there the whole time. They let this happen, they're going to kill me," he told the Post. "It's a conspiracy."

Gelman also reportedly claimed that the police choked and beat him after he was arrested and taken to the precinct.

Public defender Ed Friedman will represent Maksim Gelman, who was arraigned Sunday in Brooklyn Criminal Court on four counts of murder, one count of attempted murder, one count of assault, two counts of robbery and two counts of criminal possession of a weapon, Brooklyn district attorney's office spokesman Jonah Bruno said.

As he was led away from Brooklyn's 61st precinct to an awaiting police cruiser earlier Sunday, Gelman was deluged with questions from gathered media and hostile shouts from the crowd. After uttering an expletive, he said, "This was a set-up, man."

Authorities alleged Saturday that Gelman stabbed three people to death, hit and killed a man with a car, slashed at least five other people and carjacked two vehicles before he was wrestled to the ground early Saturday after attempting to break into the cab of a subway train.

Friedman said Gelman's case will head to a grand jury Friday.

Gelman, 23, who is unemployed and known to authorities mostly as a graffiti artist, was arrested about 9 a.m. Saturday, about 28 hours after he is alleged to have began the spree spanning three New York boroughs, Police Commissioner Ray Kelly said.

"It's so horrendous and bizarre," Kelly told reporters Saturday. "We have no reason that we can give you as to why he did this."

Police believe Gelman got into a dispute with his mother at her Brooklyn home about 5 a.m. Friday after she refused to let him take her 2004 Lexus. The suspect's stepfather, Aleksandr Kuznetsov, intervened and was stabbed 11 times, they said. Kuznetsov, 54, died, while Gelman's mother -- who survived unscathed -- alerted authorities.

Investigators believe Gelman then took the Lexus, drove about a mile away to the home of his ex-girlfriend and stabbed her mother, 56-year-old Anna Bulchenko, 11 times, about 10:30 a.m. Gelman's former girlfriend found her mother dead on the floor when she returned home about 4:15 p.m., police said. She called police.

But in the short period before they arrived, authorities believe Gelman -- who presumably was still in the apartment -- allegedly attacked the former girlfriend, ld Yelena Bulchenko, 20, with a knife. He chased her into the street and killed her, also slashing the jacket sleeve of a passerby trying to stop him, authorities said.

He then left the scene in the Lexus and rear-ended another car, a Pontiac Bonneville, allegedly stabbing its 60-year-old driver in the shoulder and neck in a confrontation and then leaving the scene in that car, police said. Authorities said they later found four kitchen knives in the Lexus.

The Pontiac driver was in stable condition as of Saturday, recovering from three stab wounds, Kelly said.

About 4:25 p.m., the car allegedly struck a pedestrian about two miles away, Kelly said. Steve Tannenbaum, 60, died of his injuries.
