Sterling Park District worker Mark Nettz had his hands full Wednesday removing graffiti at Martin’s Landing in Sterling. The vandal targeted the entrance to the bike/walking path near the Dillon Home, spray-painting graffiti that referenced Nate Edwards and Kent State. Edwards, 43, of Sterling, was shot several times in the back and killed Jan. 26 in the driveway of a Rock Falls home after a police pursuit. Police said Edwards was accelerating toward the officer who shot him, who was behind Edwards’ car. The Kent State tag refers to the Ohio college where four unarmed students were killed and nine injured by National Guard members during a protest May 4, 1970. Park District Executive Director Larry Schuldt said vandalism is occurring at about twice the usual rate this summer in city parks. He plans to discuss the possible use of security cameras with the park district’s board. Anyone with information on the graffiti is asked to call Sterling Police at 815-632-6640 or the anonymous reward hotline, Whiteside County Crime Stoppers at 815-625-7867.
