With a leg swipe, Lozito helped knock down Gelman, a grafitti vandal with at least 10 prior arrests. Lozito said that watching mixed martial arts on television helped him fight Gelman.
"I guess you watch it for 20 years, you just pick up some things through osmosis," he said.
It wasn't until Lozito sat back down on the subway bench that he realized he was bleeding. Gelman had stabbed him on his head and hand.
"When I sat up, that's when I noticed all the blood pouring down on me. I'd never seen anything like that in my life. Another person on the train, I didn't see him at all, I wish I did, he had napkins and he came up behind me and basically the whole time just pressed on this wound [on the back of Lozito's head] which I think ended up being the deepest wound back here and just stayed there the whole time with me...To me, he's my hero," Lozito said.
Gelman began his bloody rampage on Friday morning after arguing with his mother over his use of her Lexus. When his step-father, Aleksandr Kuznetsov, intervened in the argument, Gelman allegedly stabbed him to death in his family's Brooklyn apartment, police said.
Gelman then went to the home of a female acquaintance, Yelena Bulchenko, where he stabbed her mother to death, police said. He allegedly hid in the home, waiting for Bulchenko to return to find her mother's dead body. When Bulchenko called 911, he chased her out of her home, stabbing her 11 times, police said.
Gelman's spree continued. He rear-ended a car and then slashed the chest of the driver three times, police said. Gelman took the man's car and ran over a pedestrian, 62-year-old pedestrian Stephen Tanenbaum, police said. Tenenbaum died from his injuries.
In the early hours of Saturday morning, Gelman allegedly stabbed a livery cab driver and attacked a couple driving a Nissan. He stabbed the driver in his hands, hijacking the car, police said.
Gelman boarded a downtown bound subway train when a woman recognized him and alerted authorities. Gelman then ran across the tracks and boarded the same train as Lozito, police said.
Gelman was born in the Ukraine, but became a naturalized U.S. citizen five years ago, according to the Associated Press.
He had crack cocaine with him at the time of his arrest, police said.
"What's so horrendous and bizarre, we have no reason that we can give you as to why he did this," New York Police Commissioner Ray Kelly said at a press conference over the weekend.
