Prosecutors preparing to lay out their case against Penn State's former president say two of his ex-top lieutenants are among those who could take the stand.

Opening statements are scheduled to get underway Tuesday in the long-delayed criminal trial in which Graham Spanier (SPAN'-yur) faces charges of child endangerment and conspiracy. The two sides will make their openings after four alternates are chosen for the jury.

Spanier is accused of mishandling child sex abuse complaints about retired assistant football coach Jerry Sandusky. Spanier denies any wrongdoing.

On Monday, seven women and five men were chosen for the main jury panel.

The attorney general's office's witness list includes two former Penn State officials who took plea deals last week.
