The Colt family incest case, dubbed by media as the Colt incest clan, is an Australian family discovered in 2013 to have been engaging in four generations of incest beginning with "Tim and June Colt," a brother and sister who emigrated from New Zealand in the 1970s.[1] The family grew to nearly 40 members ranging from grandparents to mothers, fathers, sons, daughters, aunts, uncles, nephews, brothers and sisters all engaging in various forms of incest. Many of the children suffered from deformities and medical problems. The case has been described by lead investigator Peter Yeomans as, "like nothing I’ve ever seen," and was so shocking that in a rare move the Australian family court allowed full details to be made public, albeit with all names changed to pseudonyms for the children's protection, including the family name of "Colt."[2][3] They all lived in a farm near Boorowa, New South Wales according to NSW law case notes.
