What happened

Why it matters

The Manhattan architect and Massapequa Park schlub’s chilling guilty plea includes the slayings of seven women he had been charged with killing since 1993 — and an eighth victim newly linked to him.

Common ground

The victims’ relatives gasped in Suffolk County court as the notorious killer repeatedly answered, “Strangulation,” when asked how he murdered each of the women.

VERIFIED BY REFERENCE
