NYPD solicits DNA samples from men who frequent Howard Beach park where Karina Vetrano was killed

Denizens of the Howard Beach park where a jogger was raped and killed were asked to provide voluntary DNA samples as cops continued their manhunt for the suspect.

Men spotted hanging around the overgrown Spring Creek Park or the surrounding area were approached about surrendering a swab from their mouths, said Deputy Commissioner Stephen Davis, the NYPD’s top spokesman.
It was unclear exactly how many people were asked, or how many agreed to provide a sample. Civil libertarians have criticized the DNA gathering in the past as a police fishing expedition.

Armed with a viable DNA sample of Vetrano's killer, detectives are combing through databases for a match without success, according to police sources.
