A 35 year old father and his 3-year-old son died after the man threw the boy from the roof of a luxury Manhattan high-rise and then leaped off the building himself.

The suicide – murder happened on Sunday following what was called “domestic turmoil” with the boy’s mother, New York police said on Monday.

The father was Dmitriy Kanarikov and his son was Kirill.

Kanarikov was supposed to drop the 3-year-old boy off with his estranged wife at 1 p.m. at the precinct after a three-hour visit, as per their custody arrangement, sources said.

“Tragically, he took the son to the roof and all indications are that he threw him off and… jumped himself,” New York Police Commissioner Ray Kelly told reporters. “The mother, obviously, is very distraught.”

Kanarikov and the boys mother had been fighting over custody, after a split up in August. The mother (not yet identified) had just filed a restraining order and the father was only allowed to see his son when supervised.

This was his first visit unsupervised.

On Sunday, Kanarikov picked his son up at 10 a.m. and together they went to the South Park Tower, on Manhattan’s West Side, where an acquaintance lived. That acquaintance was not believed to have been involved in the incident and is not being investigated as an accomplice, Kelly said.

Building residents were shocked and saddened.

“How heartbreaking, how sad it is that there was no one there to stop them, to say, ‘Wait, tomorrow is another day,'” said Ellia Adiel.
