In the high-stakes world of prosecuting child sexual abuse, a prosecutor ­typically must work with little or no medical evidence, medical experts with varying degrees of expertise, a jury panel in need of education about the crime, and a victim who may (understandably) crumble on the stand. The 3rd edition of this helpful manual, updated by Harris County assistant DAs Terese M. Buess and Darin Darby, walks prosecutors of all ­experience levels through the case, from investigation to punishment phase of trial.
