Frank Atchley is a retired law enforcement officer with a distinguished career spanning decades of service. He spent twelve years as a homicide investigator before advancing to the role of investigative sergeant during the Green River serial murder investigation in King County, Washington.

This case became one of the most extensive serial murder investigations in U.S. history. Within Atchley’s jurisdiction alone, 48 women were murdered—making it the highest known victim count attributed to a single serial killer in the United States. Atchley takes great pride in his work on the task force, whose members dedicated themselves around the clock—24 hours a day, 365 days a year—to pursuing justice for the victims.

He ultimately retired at the rank of captain. Today, Frank Atchley resides in Monroe, WA with his wife.
