Jerry Sandusky trial: Prosecution rests, 1 charge dropped

The prosecution in the Jerry Sandusky child sex abuse trial rested Monday after calling the mother of one of his 10 alleged victims.

The woman told the jury she thought it odd that her son's underwear was frequently missing from the laundry, and said the former Penn State assistant football coach called her son to be a character reference for him after the first round of charges were filed in November, The Associated Press reported.

Last week, the teen testified that Sandusky forced him to have anal sex, and that he'd "just dealt with it" and thrown away his blood-stained underwear.

The woman was the last of 21 witnesses called by prosecutors over five days, according to the AP.

The defense opened its case by calling former Penn State assistant Dick Anderson.

Earlier, prosecutors dropped one count against Sandusky over a timing issue, StateCollege.com reported.

Sandusky, 68, now faces 51 counts of child sexual abuse involving 10 alleged victims over a span of 15 years. He has denied all the charges and maintained his contact with the boys was innocent.

According to CBS News, the judge on Friday granted a defense motion to allow testimony about a psychiatric condition called histrionic personality disorder. It is defined by the National Institutes of Health as a condition in which people act in a very emotional and dramatic way that draws attention to themselves.

The defense is expected to argue that Sandusky is not a sexual predator, but a man attempting to draw attention to himself with his activities.
