(CNN)–Maksim Gelman, 23, was arrested aboard a north-bound train in Manhattan around 9 a.m. Saturday, 28 hours after he allegedly began a spree across three New York City boroughs, Police Commissioner Ray Kelly said.

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

Police say the incident began around 5 a.m. Friday, when Gelman got into a dispute with his mother at her home in the Sheepshead Bay section of Brooklyn. She had refused to let him take her 2004 gray Lexus. The suspect’s stepfather intervened and was stabbed 11 times, according to Kelly. The stepfather died.

Police believe that Gelman, having then taken the Lexus, fatally stabbed the mother of his ex-girlfriend 11 times inside her Brooklyn home around 10:30 a.m.

Around 4:15 p.m., his former girlfriend — shortly after she got home — called 911 three times after finding her mother dead on the floor, police said. Gelman then went after her, eventually fatally stabbing her on the streets, police said.

Gelman then drove into a 1995 Pontiac Bonneville, stabbing that car’s driver — whom he did not know — ditching his Lexus and leaving the scene in the other car, Kelly said. As of Saturday, the Pontiac driver is in stable condition at a local hospital, police said.

Some time soon thereafter, Gelman drove the Pontiac into a pedestrian in the Midwood section of Brooklyn, Kelly said. The man later died of his injuries.

The suspect eventually abandoned the Pontiac. Shortly before 1 a.m. Saturday, according to Kelly, Gelman hopped into a cab in Brooklyn and stabbed its driver. That man is also in stable condition at a local hospital.
The commissioner said Gelman then got out of the cab and confronted a couple, stabbing a 25-year-old man in the hands and taking his keys to a Nissan. That man, who Kelly said suffered only defensive wounds, was treated and released at a hospital.

Then, around 8:30 a.m. Saturday, New York police got a phone tip that Gelman might have been riding on a southbound subway train in Manhattan.

Soon thereafter, he switched to a northbound express train. While on the train, Gelman stabbed a man in the head and neck, according to Kelly. That man is also in stable condition.

Eventually, the suspect worked his way to the front cab of the train, where the conductor and two police officers were looking for Gelman. The commissioner said that Gelman pounded on the cab’s door, yelling “Police” — apparently trying to get in by claiming he was a police officer.

Soon thereafter, the two police officers — with aid from an off-duty detective and a civilian nearby — wrestled Gelman to the ground. No one was hurt in the scuffle.

As of Saturday afternoon, Gelman had not yet been charged with any crime and was in a Manhattan police precinct.

Kelly said that Gelman had 10 previous arrests, mostly for drug charges and graffiti, plus one robbery charge. His most recent arrest came on January 26, when he was accused of possessing crack.
