In another article on this story, they said that the husband reported the woman missing in 1965. Police later learned that she hadn’t actually been seen since 1961. This probably struck them as a tad suspicious.
Anyway, before I feel too bad that husbands are eyed in cases like this, I’d have to know: When a married woman mysteriously vanishes or is murdered - how often is it the husband?
It is very strange if he waited 4 years to report.
