Police have a "person in custody" in connection with the brutal slaying of Queens jogger Karina Vetrano, an NYPD source confirmed late on Saturday night.

The person is in his 20s and lives in public housing in East New York, according to media reports.

"We know they have the person of interest in custody. That's all I can confirm right now," said Karina Vetrano's father, Phil Vetrano, ABC7 reported.

“I’m literally shaking right now,” a close friend of Vetrano’s told the New York Daily News. “I want to see his face. I want to see if I know him.”
