Custody fight ends in father-son murder-suicide from 52nd floor

An unhinged man involved in a bitter child-custody battle tossed his toddler son to his death from the roof of a 52-floor building on the Upper West Side Sunday, then�🍷� killed himself by jumping, law-enforcement sources said.

Dmitriy Kanarikov, 35, of Brooklyn, was supposed to drop off adorable 3-year-old Kirill with his estranged wife at 🥂1 p.m. at the 17th Precinct station house on the East Side after a three-hour visit, as per their custody arrangement, sources said.

Instead, surveillance footage from the scene at 124 W. 60th St. shows the dad leading the chi꧒ld by the hand into the high-rise building at 🃏around 11:45 a.m., according to law-enforcement sources.

Kanarikov, a systems developer, the𝓡n went to the top of South Park Tower with the red-haired tot and pitched the boy to his death before making his own fatal leap at around 12:05 p.m., sources said.

Kanarikov fell onto a fourth-floor landing 🦩of a John J🐻ay College building next door and died instantly, sources said.

The child — dressed in light-blue pants, a white-and-orange striped shirt, “Cars’’ socks and a little blue rain coat — was found on a sixth-floor landing. He was rushed in cardiac arrest to Roosevelt Hospital across the street, but it was hopeless, sou𝄹rces said.

“✤They were pumping his chest and working on him, and nothing” said Luis Ortiz, who was at the hospital when paramedics rushed the child in. “It was just heartbreaking . . . They tr🎉ied to do the best they could.”

The child’s mother, Svetlana, “is a mess,’’ said a law-enforcement source. She told cops that her husband had previously “thre𝓀atenedꦍ to kill himself and then kill our child,” a source said.

Only months earlier, the couple and their son appeared to be the picture of happiness. In March, Svetlana wrote on Facebook, “I have the bes﷽t husband and son in the world.” The doting parents’ posted a video on the Web site of their smiling, blue-eyed son in footie truck pajamas growling into a book, with his mom writing, “This is what happens when we do a bedtime story.’’

Another video shows the boy brushing snow off the bu⛄mper of a car as his father proudly looks on.

Heartbreaking photos from a recent trip to the beach show the boy clingin♛g to Kanarikov’s leg with🏅 Svetlana smiling in the background.

“It looked like that kid was h♚is world, a neighbor of Kanarikov’s parents ✃in Brooklyn said Sunday.

“He was a serious guy. He didn’t smile much. But when he was with the ki꧋d, he always look𝕴ed happy.”

Svetla😼na, a mathematician and violinist, and Kanarikov, who worked for the financial-services firm TIAA-CREF, were married for four years 𒅌before splitting in August, sources said.

She told cops Sunday that her husband was abusive and that they had squabbled over money, sources said. At one point, both she and the child had an order of protection against K𒁃anarikov, but that was lifted in S♌eptember, sources said.

In a September Facebook posting, Kanarikov wrote, “I want to be the best dad and husband. Nothing is more important to me right 𝄹now.”

Kanarikov, an immigrant from Uk🦂raine, had a male pal who, until two months ago, lived in the Upper West Side building where the tragedy occꦓurred and used to visit him there, sources said.
