BELLEFONTE, Pa. (MCT) — A psychologist testifying for Jerry Sandusky’s defense is expected to present a novel defense soon on behalf of the former football coach: He has a “histrionic personality disorder,” characterized by an excessive need for attention, and that condition explains his e-mails and “grooming”-type behavior toward his alleged victims.

Sandusky is facing multiple charges involving sexual crimes against children, and as soon as Tuesday, the defense could call a psychologist, arguing that Sandusky suffers from a disorder whose symptoms include exaggerated expressions of emotion.
