連環殺手受害者數量列表

美國聯調局（FBI）對連環殺手（serial killers）的定義是：謀殺至少3個人，並在作案期間存在“冷卻期”，與短時間內，在同一地點展開大屠殺的大規模殺手（mass murderers），又或四處逞兇殺人的瘋狂殺手（spree killers）有別。所謂“冷卻期”，就是指兩宗謀殺間隔的那段時間，連環殺手這段喘息的時間長短不一，短的可為1、2天甚至是幾個小時的，長的有1個月甚至數月，通常連環殺手通過一次“謀殺體驗”使自己興奮情緒達至一個高峰後，需要一段時間平靜下來，回味並總結這段亢奮經歷，改良行兇方法。 已查明的連環殺手大部分都是有組織型和反社會型的，他們通常智商很高，從外表根本無法判斷他們是殺人狂。連環殺手一般都是單獨行動，殺害的都是陌生人，且多是在無人知曉的情況下殺人。他們作案並不是一時興起，動機也不是出於嫉妒或貪婪。
