美国堪萨斯州温菲尔德市53岁男子罗纳德·威廉姆斯于周二上午8:50致电警方，称已杀害全家成员[1]。警方随后赶到现场，在上午11时破门进入[1]，发现威廉姆斯及其伴侣凯利·乔治（44岁）以及他们的四个孩子——卡罗尔·威廉姆斯（9岁）、罗纳德·威廉姆斯二世（7岁）、莎拉·威廉姆斯（5岁）和凯利·梅吉-威廉姆斯（3岁）共六人遇难[1]。
威廉姆斯曾是注册性犯罪者，1999年因两项重罪指控认罪[1]。据警察局长罗比·德隆表示，威廉姆斯在近数周表现出"攻击性行为"[1]。这起事件是中西部地区两周内发生的第二起家庭灭绝案件，此前密歇根州曾发生克里斯托弗·卡罗尔基维茨射杀妻子和六个孩子的类似案件[1]。根据统计，美国今年已发生15起大规模枪击事件，其中至少9起符合"家庭灭绝"的定义[1]。
A 53-year-old man in Winfield, Kansas called police at 8:50 a.m. on Tuesday to report that he had killed his family, then shot himself [1]. When police tactical units breached the home at 11 a.m., officers discovered six bodies: the suspect Ronald Williams, his 44-year-old partner Kelly George, and their four children—Carroll Williams, age 9; Ronald Williams II, age 7; Sarah Williams, age 5; and Kelly Meggie-Williams, age 3 [1].
Police Chief Robbie DeLong stated that Williams had exhibited "aggressive behavior" in recent weeks [1]. Williams was a registered sex offender who pleaded guilty to two felony charges in 1999 [1]. The incident marked the second such family homicide-suicide in the Midwest within two weeks, following a similar killing in Michigan where Christopher Carrol Kwiatkiewicz shot his wife and six children [1]. The tragedy brought the total number of mass shooting incidents in the United States this year to 15, with at least nine meeting the definition of "familicide" [1].
