Although case studies can provide insight into children's eyewitness memory
, the typical lack of objective record limits evaluation of accuracy. In co
ntrast, in this 'scientific case study', a detailed record of child sexual
assault, documented by a 'sex ring' leader and confiscated by police, was a
vailable. In police interviews and courtroom hearings, four girls (8 to 15
years old at time of report) testified about sexual exploitation that invol
ved eight adult men. The girls' allegations were compared with evidence con
tained in photographic and audiotaped records of the abuse. Overall, there
was supportive evidence for about 80% of the allegations (85.6% of the alle
ged sexual acts; 42.9% of the alleged coercive acts; and 82.5% of the alleg
ed preparatory acts). Levels of support for sexual act allegations were sim
ilar for all four girls, regardless of age, but the younger child made more
unsupported allegations of coercive behaviour. Additionally, there were hi
gh levels of omission errors. Findings are discussed in the context of rese
arch on eyewitness testimony and child sexual abuse. Copyright (C) 2000 Joh
