Indeed and Without Doubt
It wasn’t until much later that DNA evidence recovered in 1992 would lead to the exoneration of both Brooks in 2001 and Brewer in 2008. This DNA belonged to Justin Albert Johnson, who confessed to both crimes but denied having bitten either girl. This statement is consistent with Dr. Souviron’s conclusion about the marks not being bitemarks as well. Rather, as it turns out, the marks found on the girls’ bodies were insect bites.
Taking a chance with chances
The investigators’ line of reasoning was based on the assumption that for the bite marks on the body and the ones produced by Krone on the Styrofoam to match, they must come from the same source. This is called the assumption of individualization. However, this assumption leads to fallacious thinking.
