A Centennial man who pleaded guilty in January to two counts of sexual exploitation of children will stand trial on a total of five charges beginning in May.

In a ruling issued Wednesday, District Court Judge Jeffrey Donnell allowed 18-year-old Nathaniel Lane Wamberg to withdraw his guilty pleas.

Prosecutors dropped three other charges of the same nature in exchange for Wamberg’s guilty pleas, but Donnell ordered those charges reinstated for trial.

Wamberg will face all five original charges of sexual exploitation of children at trial. If convicted on all counts, he could be face a maximum penalty of 50 years in prison and $50,000 in fines.

Wamberg will stand trial beginning at 9 a.m. May 19 in Albany County District Court. The trial is scheduled to last two days.
