Dexter-style kill room revealed in Rex Heuermann's basement, prosecutors say

Prosecutors say Rex Heuermann kept a 'Dexter'-style kill room in his Long Island basement, with infrared/ultraviolet evidence revealing adhesive stains forming a square and a planning document labeled 'HK' detailing supplies, tapes, and routes; Heuermann pleaded guilty to seven murders and confessed to an eighth, receiving three life terms without parole plus four more 25-to-life terms. Victims’ families offered emotional statements as investigators cited phone data and a shift from disorganized to organized MO, aided by digital evidence and a Mindhunter book Heuermann studied.
