As many as 1,000 police and fire vehicles are expected to form a procession through the Eugene- Springfield area on the way to Friday’s memorial service for slain Eugene Officer Chris Kilcullen. The service is scheduled for 2 p.m. at the University of Oregon’s Matthew Knight arena, which has room for more than 12,000 people to attend. KBND talked with a friend who will be speaking at the memorial. Eugene radio talk show host Rob Holloway is speaking at the service. He says officer Chris Kilcullen was a friend who made a big difference in their local community. “He was in traffic enforcement and hostage negotiations, and was extremely involved in with Relay for Life with the American Cancer Society. He never said 'no' and was so involved with causes. If you had a good cause and a cup of coffee, he was there and he'd give you 3 times what you'd ask for."   He was shot and killed a week ago. Cheryl Kidd, 57, a Springfield woman is charged with aggravated murder.  Kilcullen is the first Eugene Officer killed in the line of duty since 1934.
