Closing arguments are set for today in the child sex abuse trial of Jerry Sandusky.

The defense rested on its third day today without calling the former Penn State assistant coach to dispute the charges against him.

Sandusky is accused of molesting boys at his home and on campus for more than a decade.

The defense called only four new witnesses today. They included a physician who they used to try to poke holes in the story of a Penn State coaching assistant who testified that he saw Sandusky sexually assault a boy in the campus showers.

Sandusky is charged with 51 criminal counts for the alleged abuse of 10 boys over 15 years.

Judge John Cleland said jury instructions and closing arguments by the defense and then prosecution would take place in the morning. If convicted, the 68-year-old former defensive coordinator could be sent to state prison for the rest of his life.
