The team of journalists who produced The Oregonian/OregonLive’s groundbreaking series “Ghosts of Highway 20” are giving two free talks about the project in October.

Reporter Noelle Crombie, videographer Dave Killen and photojournalist Beth Nakamura, along with project editor Margaret Haberman, will appear Oct. 3 from 6 to 7:30 p.m. at the Hollywood branch of the Multnomah County Library, 4040 N.E. Tillamook St. Seating is first come, first served.

The team will also appear Saturday, Oct. 19, at 3 p.m. at the Hillsdale branch, 1525 S.W. Sunset Blvd., Portland. The events are free and do not require registration.

The journalists will discuss the yearlong project, which revealed for the first time that John Ackroyd was an Oregon serial killer. Killen produced a five-part video, which has more than 1 million views to date.
