Operation Trinity: Continuing suspicions in several other unsolved murders
An inter-force review known as Operation Trinity examined several murders of women committed in Scotland in the 1970s. Sinclair was considered a major suspect, notably in the murders of Anna Kenny, Hilda McAuley and Agnes Cooney. Investigators and profilers considered the links strong, but available evidence did not permit further prosecutions.
