Detectives are grilling a man in the killing of Queens jogger Karina Vetrano, police sources said Saturday.
Vetrano, 30, was raped and strangled as she ran through Spring Creek Park in Howard Beach on Aug. 2.
Her death sparked a massive manhunt for her killer as well as a push to have state authorities allow familial DNA testing.
Police recovered her killer’s DNA from Vetrano’s body, but the sample did not match anyone in the New York and national DNA databases of convicted criminals.
Familial DNA testing would allow investigators to find a partial match possibly a relative of the killer.
The circumstances behind the suspect’s capture were not immediately disclosed.
