McMartin Preschool The McMartin Preschool case was the first daycare abuse case to receive major media attention in the United States. The case concerned the McMartin Preschool in Manhattan Beach, California, where seven teachers were accused of kidnapping children, flying them in an airplane to another location, and forcing them to engage in group sex, as well as forcing them to watch animals being tortured and killed. The case also involved accusations that children had been forced to participate in bizarre religious rituals, and being used to make child pornography. The case began with a single accusation, made by a mother—who was later found to be a paranoid schizophrenic—of one of the students, but grew rapidly when investigators informed parents of the accusation, and began interviewing other students. The case made headlines nationally during 1984, and seven teachers were arrested and charged that year. However, when a new district attorney took over the case in 1986, his office re-examined the evidence, and dismissed charges against all but two of the original defendants. Their trials became one of the longest and most expensive criminal trials in the history of the United States, but in 1990, all of these charges were also dismissed. The trial was met with disapproval by both its jurors and academic researchers, who criticized the interviewing techniques that investigators had used in their investigations of the school, alleging that interviewers had "coaxed" children into making unfounded accusations, repeatedly asking children the same questions, and offering various incentives until the children reported having been abused. Most scholars now agree that the accusations these interviews elicited from children were false. Sociologist Mary de Young and historian Philip Jenkins have both cited the McMartin
