On Aug. 2, 30-year-old Karina Vetrano was strangled to death while jogging alone on a path where she and her father often ran together in Howard Beach, New York.
Because nothing came of surveillance video, police are relying on witness recollection; they have been interviewing joggers and bicycle riders every day.
As police released the witness sketch today, Boyce emphasized that the witness is not a suspect or a person of interest but that he was allegedly in the area at the time of the murder and police want to speak to him.
The witness is described as a black man age 35 to 45 who was wearing a wool cap. He stands about 5 foot 10 and has a medium build.
The sketch was prepared by utility worker who was working in the area at the time.
Vetrano's devastated parents addressed the media on Aug. 18, pleading with their daughter's killer to own up to the crime.
"I know that you're tormented," her father, Phil Vetrano, said. "I know that you're being driven crazy. I know that you want to do the right thing."
"My little baby was brutalized by this person, by this evil coward," her mother, Cathy Vetrano, said. "Her last moments were horrible."
Cathy Vetrano then addressed the killer directly, saying, "Show someone that you care about that you're not as evil as the whole world thinks that you are. You can't run. It's just a matter of time."
