The I-5 Killer, Randall Woodfield, was an American serial killer, rapist, and robber who operated along the Interstate 5 corridor in Oregon, Washington, and California during the 1970s and early 1980s. He was convicted of murder and was suspected of involvement in numerous additional killings. His crimes inspired Ann Rule’s true-crime book The I-5 Killer.
