The Glens Falls Police Department is investigating the dumping of what is believed to be a substantial amount of driveway sealer in Crandall Park. A trail of sealer was found running along the ground near the community picnic pavilion, just south of the park’s playground. WTEN reports police are looking for a suspect believed to have visited the area between 7:30 and 8 a.m. on Wednesday morning. The person is described as a white male wearing a straw hat, seen driving a blue pickup truck with a white tailgate carrying large drums.
