Fifty-year-old Sergey Mamontov of 3395 Nostrand Avenue in Sheepshead Bay has confessed to dismembering his roommate because, he felt, "there was no other way to take care of [the victim]," police sources told the Daily News. Mamontov had squabbled about noisiness and partying with his 55-year-old roommate Aleksandr Zilbergleyt, who had been living there for about eight months. A person living in the building reported hearing a loud crashing sound on March 25, the day Zilbergleyt disappeared. “He was very meticulous, very methodical,” a source told the Daily News. “He cleaned up afterwards. He put the body parts in the refrigerator ... He didn’t know what his next move was." Police found Mamontov watching TV when they arrived at the residence.
