A longtime advertising employee of the Union Leader was shot and killed in a Manchester neighborhood Sunday night.  Police say 62 year old Denise Robert of Bedford, was shot and killed last night on Ray Street. Neighbors said they heard a shot about 8:50 p.m.  Police Chief Nick Willard said he hesitated to call the shooting random because Ray Street is a quiet neighborhood that is considered safe. Willard said witnesses described seeing a pickup truck leaving the area at a high rate of speed. The driver described as a white man in his 20s or 30s, with close-cropped hair wearing a white tank top.
