Investigators in Princeton, Massachusetts, say one month after the murder of Vanessa Marcotte, they have now received more than 1,000 tips in the case but still have not made any arrests.
Marcotte was killed while jogging near her mother's house on August 7.
Area residents remain on edge knowing Marcotte's killer is still out there.
"We don't know if they're here, we don't know if they've moved on," said resident Barry Sherman. "Just that a human being could do that to another person is just very unsettling."
Police have been looking for a man who may have been spotted driving or parked on Brooks Station Road between 1-3 p.m. the day Marcotte was killed. Investigators say that's where the New York resident's body was found naked and burned.
"We're just amazed that this has happened," said resident Karen Sherman. "We have a daughter that age and our heart breaks for everyone involved."
About two weeks ago, necn interviewed a man who said police questioned him and took his DNA in connection with the case. He's denied any involvement.
Police haven't said whether that man is a suspect.
Residents are holding on to hope that justice will be served.
"That is our hope, that they will find someone and bring justice," said Sherman. "That's the only way i think everyone in this community will be able to sleep at night.
Investigators say they have been working around the clock and will not rest until they find justice for Vanessa and her family. Anyone with information is urged to call their tip line at 508-453-7589.
