Jerry Sandusky, the former Penn State coach who has been charged with over 50 counts of child sexual abuse spanning 15 years, waived a formal arraignment that had been scheduled today in a Centre County (Pa.) courthouse.

Sandusky not appear in court. In today’s proceeding, the presiding judge set a series of deadlines by which attorneys must file their pre-trial motions. Informal discovery, in which prosecutors must turn over evidence to the defense, must be completed by Jan. 16, the Harrisburg Patriot-News reported.

Last month, Sandusky waived his right to a preliminary hearing in a very brief court appearance.

Other key dates:

•Feb. 1 is the deadline by which a request — from either side — for a change of venue must filed. This is also the date by which either side must file a request to bring in jurors from another county.

•March 1 is the date by which any other pre-trial requests must be filed.

•On April 5, the judge will hear arguments about pre-trial issues.

Sandusky is next expected to appear in court March 22 for a pre-trial conference. At that time it should be clear whether the parties are ready to set a trial date.

The Patriot-News reports that the earliest the case could go before a jury is in the April/May term of the Centre County court.
