On October 31, 1969, Patricia Spencer (16) and Pamela Hobley (15) vanished from Oscoda, Michigan. Both skipped school and were last seen walking along River Road, possibly heading to a homecoming game or Halloween party. Patricia was vibrant and family-oriented; Pamela was rebellious, recently engaged, and rumored to use drugs. Initially considered runaways, police later concluded they were likely abducted while hitchhiking and murdered. A motorist’s report of giving them a ride and a 1985 tip about their murder near a barn were ignored until 2010, when Chief Mark David reopened the case. Searches yielded no evidence, and a 2013 person of interest led nowhere. Theories link the case to serial killer Rodney Alcala (due to a photo resembling Pamela) and the Oakland County Child Killer, but neither fully fits. The case remains unsolved, with no bodies or closure.
