Police have released new surveillance video showing what may have been Karina Vetrano's final moments on Aug. 2 before she was found killed near her home in Queens.
The video shows Vetrano jogging near her Howard Beach home. She was later found sexually assaulted and strangled in a marshy area just off the trail at Gateway National Recreation Area.
NYPD Commissioner Bill Bratton said Monday the release of the new video is an effort to keep the case fresh in the public's mind.
"It remains one of the unsolved, very high-profile murders," he said.
A reward of nearly $300,000 is being offered for information leading to an arrest.
Late last month, police released a sketch of a man in a woven wool cap they want to talk to in connection with Vetrano's death. The man was seen in the area around the time Vetrano went missing.
Police officials stressed at the time that the man wasn't a suspect or a person of interest in the case. The man was seen in the area around the path where Vetrano was last seen that day and was spotted by a utility worker. Police said that the man could have seen Vetrano or her assailant.
Authorities have culled DNA from three different investigative points -- Vetrano's neck, her phone and her fingernails. Police say the fingernail DNA is the strongest, and all the samples point to the same person, though the state and local databases have yet to yield a possible match.
Anyone with information on the Vetrano case should call Crime Stoppers at 1-800-577-TIPS.
