The cook brothers from Toledo, Ohio acknowledged taking part in the slayings of nine people during the 1970s and early 1980s.

Anthony Cook, 51, said he was involved in all nine slayings, meaning he either killed the victims or encouraged his brother to do so. Nathaniel Cook, 42, admitted he had a role in three killings.

Both brothers were long-haul truck drivers and spent time in several states.

Anthony Cook spent time driving through Ohio, Illinois, Indiana, Michigan and Texas before he was sent to prison in 1981. There is much speculation about other victims.
