The NYPD released Wednesday a sketch of a witness they want to identify and question in the murder of Queens jogger Karina Vetrano.

In the month since her death no suspect has been identified and there has been little progress in the investigation, despite approximately 85 tips submitted to police, ABC News reported.

Vetrano, 30, was found raped and strangled to death on Aug. 2 alongside a path she frequently ran with her father in Howard Beach.

Chief of Detectives Robert Boyce said the killing is believed to be a random attack, and emphasized that the witness depicted in the sketch is not a suspect or person of interest, but was allegedly in the vicinity at the time Vetrano went missing.

The witness was described by a utility worker reporting to the sketch artist as a black man, between the age of 35 and 45, and is about 5 feet 10 inches and of medium build.

The victim’s parents, Phillip and Cathie Vetrano, had set up a GoFundMe page that has raised more than $250,000 as a reward to anyone with information leading to an arrest. Last week the office of Mayor de Blasio added another $10,000 to the $25,00 reward being offered for information about the killing.

Anyone with information in regards to this witness or Vetrano's murder is asked to call the NYPD's Crime Stoppers Hotline at 1-800-577-TIPS (8477). The public can also submit their tips by logging onto the  Crime Stoppers website or by texting their tips to 274637 (CRIMES) then enter TIP577. All calls are strictly confidential.
