OTTAWA — Putnam County Sheriff Brian Siefker announced the creation of a safe exchange zone Tuesday. The zone is a few parking spots in the Putnam County Sheriff’s Office parking lot at 1035 Heritage Trail, Ottawa. The parking spots are well lighted and under camera surveillance, Siefker said. The cameras are set up so the license plates of each vehicle can be seen and the exchange can also be monitored in real time from the dispatch room, he said. “We just wanted people to have a sense of security,” Siefker said.
