"Sometimes, my mind isn't right," Maksim Gelman, 23, told reporters.
The words came in a disjointed torrent of talk Tuesday and were peppered with the 6-foot-2, 260-pound man's thoughts on an alleged conspiracy theory that he believes is being plotted against him by the government.
"The DEA set me up. They let this happen. They were there the whole time," a barely coherent Gelman rambled. "If you are who you say you are, you have to look into this. The proof is in the pudding."
Gelman alleged he was abused while in police custody. "They are going to kill me," he said, adding, "I'm trying to make my peace with God."
Roughly three minutes into his rants, Gelman accused the reporters in the room of being a part of the conspiracy against him. With that, he abruptly jumped up and walked away.
Is Gelman working on a trendy alibi or does he truly suffer from a mental disorder? The answer to that is not yet known and will likely take a team of psychiatrists months, possibly years, to figure out.
Gelman, of Brooklyn, is accused of going on a 28-hour stabbing rampage through New York City last week. Police say he killed his mother's boyfriend, Aleksandr Kuznetsov, 54; Steven Tannenbaum, a 60-year-old pedestrian; Anna Bulchenko, 56; and her 20-year-old daughter, Yelena Bulchenko, who her friends say he was obsessed with.
Gelman has been arraigned in Brooklyn Criminal Court on four counts of murder, one count of attempted murder, robbery charges and two counts of criminal possession of a weapon.
Earlier Tuesday, cars jammed Flatbush Avenue near Arbat Memorial Chapel in Marine Park in Brooklyn as roughly 1,000 mourners paid respects during a joint mother-daughter funeral for the Bulchenko women.
Yelena Bulchenko's boyfriend, Gerard Honig, 24, also spoke during the chapel service. Quiet sobs filled the room as he spoke passionately about his love for the woman he had been dating for the past several months.
"Never would you see her without a smile," Honig said. "I hope she's looking down on us now and helping us with everything. I love her with all my heart."
The anguish Honig expressed was shared by the victim's distraught family and friends.
"This is honestly the biggest tragedy I ever went through, and I'm truly at a loss of words at the whole situation," Yelena Bulchenko's friend, Jessica Sartini, told AOL News.
Anatoliy Bulchenko, the husband of Anna Bulchenko and the father of Yelena Bulchenko, approached the twin mahogany coffins during the memorial service and knelt between the bouquets of flowers that surrounded them. After laying his head on his wife's chest, Bulchenko turned to kiss her but was unable to and collapsed to the floor in tears.
The bodies of the victims were taken to be buried at Ocean View cemetery on Staten Island, a tranquil ending to a horrifying week.
"Yelena was a good girl, and I can't even think of any ... reason why anyone would ever want to hurt her," Sartini said. "All she had was love for her friends and family. I just hope that she gets justice for what was done to her and her mother, and all the other victims."
Sartini added, "As far as me and my friends, I speak for them all when I say that a link from the chain is broken, but the bond remains strong with all of the memories we shared together."
