William Strampel, who until December was dean of the College of Osteopathic Medicine, also was charged with failing to enforce or monitor protocols set for Nassar after a female patient complained of inappropriate sexual contact.

After the apology, Judge Rosemarie Aquilina read parts of a letter, written by Nassar to her, to the courtroom to explain her serious and lengthy sentence.

His accusers said he would molest them while they were on a table seeking help for various injuries. Nassar also has a 60-year prison sentence for child pornography crimes.
