"We have a killer walking the streets in the city of Manchester, he could do it again," said victim Denise Robert's brother Tom.
It's been one year since 62-year-old Union Leader sales rep Denise Robert of Bedford, New Hampshire was shot and killed while on her usual Sunday night walk in her childhood neighborhood in the North End of Manchester.
Robert's eleven brothers and sisters still hoping for closure for their eldest sibling who took care of them growing up.
Tom Robert said, "We all hoped for a quick resolution but it hasn't come."
While police say tips continue to come in on the unsolved murder almost weekly, no one has been charged.
Manchester, NH police Chief Nick Willard said, "The detectives that are investigating this case, they wear it as a weight on their shoulders everyday, it's what they think about when they wake up, it's what they think about when they're at work, it's what they think about when they get home."
The attorney general's office is still hoping to talk to the white male in his 20's or 30's driving a dark colored pick up truck seen quickly leaving the area of Ray and Carpenter Streets around the time of the murder.

But they say any tip, no matter how small, may help.
Assistant Attorney General Geoffrey Ward said, "It is a needle in a haystack, but what's important is to keep pushing and keep pressing because information can start to come in, people who were scared for whatever reason may now be comfortable providing information, you never know what will lead to someone slipping up."
Tom Robert said, "It may be a small bit of information that may make the whole puzzle fit."
A walk and candlelight vigil is scheduled for 6:30pm Thursday at the Brookside Congregational Church, where Robert last parked her car.
Manchester Crimeline is still offering a $40,000 reward for information leading to the killer's arrest.
