An Oklahoma man facing child molestation charges back home turned himself in to the NYPD on Friday for allegedly killing an older romantic partner on the Upper East Side.

Alex Scott, of Tulsa, turned himself in just after midnight at the 19th Precinct stationhouse on East 67th Street, police said.

Scott, 24, made “incriminating statements” to cops about the death of Kenneth Savinski, 64, who was discovered by a pal Wednesday at 5:20 p.m. in his apartment on East 83rd Street near Lexington Avenue, according to a high-ranking source.

Police found him face down and covered in blood on his living room floor. His throat had been slit, and he had been stabbed several times on his forehead, neck and face, police said.

Scott met Savinski, who is more than twice his age, on a dating app, according to a high-ranking police source.

As the pair rendezvoused, there was a warrant out for Scott’s arrest back in Tulsa, where he is facing charges for molesting a five-year-old boy in September 2018.

It was the second time Scott managed to flee Oklahoma for New York.

The fugitive first arrived in town during the fall of 2018 after the molestation allegations surfaced, according to Tulsa prosecutors.

He drove 1,400 miles to Long Island, where East Hampton police spotted and arrested him in October that year on a warrant for the charges back home. He had told police at the time he was driving to Montauk to commit suicide, prosecutors said.

Scott was brought back to Tulsa, where he pleaded not guilty. He was jailed for eight months before he managed to post bail last July.

Scott was released with an ankle bracelet, under the condition that he would report back to court weekly.

But authorities noticed Scott had missed several check-ins and a warrant for his arrest was issued on Tuesday last week — eight days before Savinski was found dead.

Mourners paid respect to Savinski Friday, placing flowers at his doorstep with the message, “RIP Kenny, you will be missed.”

“It’s scary to think that it could happen here in this neighborhood, which is a very safe neighborhood,” said Virginia French Belanger, 65, who lives in the building.

Savinski worked in sales and was a genial, dapper man — always seen in a sport coat, according to shocked neighbors passing the typically quiet uptown block.

He frequently attended mass at the nearby Park Avenue’s Church of St. Ignatius of Loyola.

“He seemed like a jovial, sort of an upbeat fella, very pleasant,” said neighbor Richard Combes, 56.

Police don’t believe Scott broke into Savinski’s home.

Scott is expected to be charged with murder, five counts of grand larceny and five counts of criminal possession of stolen property.

He was found in possession of Svanskiy’s credit cards, which he had used to make purchases on, according to a police source. It is unclear what he bought.
