The New Hampshire Attorney General's office is investigating a homicide in Manchester.
Manchester Police said the victim of the Sunday night shooting was Denise Robert, 62, of Bedford, a longtime member of the advertising sales department at the Union Leader newspaper in Manchester.
Robert was shot shortly after 9 p.m. while she was going for her usual Sunday walk after stopping at several locations, including Vitamin World, Walmart and Hannaford, police said. She had parked her car in the area of Carpenter and Ray streets and was walking in the neighborhood when she was shot. She died of a single gunshot wound.
Police said they aren't sure if a robbery or an attempted robbery might have led to the shooting. They said they won't know what the motive was until they are able to locate the shooter.
"I believe there's some sort of intent here. I just don't know what it is," Manchester Police Chief Nick Willard said. "We are going to explore every possibility."
The suspect is described as a male in his 20s or 30s, with close-cropped hair, possibly wearing a white tank top T-shirt. He is believed to have been driving an older model pickup truck, possibly rusting.
Robert had worked at the Union Leader since 1983.
"Denise dedicated her life to the Neighborhood News and New Hampshire Union Leader and left an indelible contribution," Steve Pare, advertising manager at the Union Leader, said in a statement.
"No one cared more about Neighborhood News and the New Hampshire Union Leader than Denise Robert. She worked tirelessly and cared deeply about her customers and co-workers. Her memory will live on and she'll be deeply missed but never forgotten."
Willard said he's learned that Robert was "an extraordinary individual... Her loss is going to be felt."
The chief said he will hold a neighborhood meeting on Monday night, and a stress counselor will be present to help people cope.
"I don't think people should be living in fear," he added. "I think people should be living cognizant of their surroundings."
Anyone who may have seen Robert on Sunday night or who has any information on the suspect is asked to call Manchester Police at 603-668-8711.
