The relationship that supposedly drove lovelorn Maksim Gelman's bloody rampage was a figment of his imagination, friends of the woman he obsessed over said Sunday.
"That was all in his head," said Yelena Bulchenko's pal Andrey Andriak. "They were never a couple - barely friends. He wanted to take it to the next level and she didn't."
Gelman's fixation turned to murder Friday when he stabbed the 20-year-old Bulchenko to death outside her Sheepshead Bay home.
He had already fatally stabbed his stepfather and Bulchenko's mother and went on to kill a pedestrian and wound five others in a 28-hour killing spree.
Those who knew Gelman said he had harassed Bulchenko for months after she spurned his advances.
"He became obsessed with her. He would call and text her all the time, but she would never answer back," said college friend Lauren Vasquez. "He didn't get it. It was all in his head that they were together or would be together."
Neighbors said Gelman was a lowlife who was often stoned on angel dust. Police said he had a string of arrests for drug possession and other charges.
"He's just a deadbeat with nothing else on his mind," said Karina Mkrtchian, as she lit a candle at a makeshift memorial outside the Bulchenkos' home.
"She was happy. There was nothing wrong," she said.
Bulchenko worked as a receptionist at a dentist's office and had been working toward becoming a nurse.
"She and her mother were really close. She was a really nice person and so was her mom," Vasquez said. "Her mother cared about all her friends."
