A civil suit against Jerry Sandusky was filed Wednesday morning in Philadelphia, by a man alleging the former Penn State assistant coach sexually abused him more than 100 times over a period of four years.

Sandusky has been charged with 40 counts of various sexual crimes against children. The charges were announced earlier this month in a grand jury presentment, which found that eight young men were the targets of sexual advances or assaults starting in 1994 and continuing through 2009.

But the plaintiff -- known in the suit only as John Doe A -- is not one of those eight identified in the grand jury report. The suit is the first of several expected to be filed in the Sandusky case. It lists Sandusky, Penn State, and The Second Mile -- the charity Sandusky founded -- as defendants.

The suit says Sandusky met the plaintiff through the Second Mile in 1992, when the plaintiff was 10 years old, and sexually abused him between 1992-96.

The plaintiff alleges Sandusky sexually abused him more than 100 times, in multiple locations. Those include the football coach's locker room at Penn State, at facilities out of state connected with a Penn State bowl game, and at Sandusky's home.

It said Sandusky threatened to harm the plaintiff's family if he told anybody about the abuse.

As a result of Sandusky's actions, the suit said, the plaintiff has "suffered and continues to suffer great pain of mind and body, shock, emotional distress, physical manifestations of emotional distress, embarrassment, loss of self-esteem, disgrace, humiliation, and loss of enjoyment of life."

The plaintiff has also been unable to perform daily activities, experienced a loss of earnings, and incurred expenses for therapy.

It asks for a financial reward in excess of $400,000 for childhood sexual abuse, negligence and civil conspiracy to endanger children, among other counts.

The suit says that had Penn State and Second Mile not been negligent, they could have prevented Sandusky from abusing many children, including the plaintiff.
