UPDATE: Larry Nassar sentenced to 60 years in prison

UPDATE: Larry Nassar has been sentenced to sixty years in prison on federal pornography charges. 6 News is in the courtroom and will update this story online and on 6 News.

GRAND RAPIDS, Mich. (AP) – A Michigan sports doctor who admits he molested gymnasts and kept a staggering collection of child pornography is getting the first of three prison sentences that will likely keep him locked up for decades.

Larry Nassar is returning to federal court Thursday in Grand Rapids for his pornography sentence. He’ll be punished in January in state court for sexual assault.

Nassar worked at Michigan State University and at USA Gymnastics, the Indianapolis-based group that trains Olympians.

Federal prosecutors are seeking a 60-year sentence. Investigators found more than 37,000 images of child porn on Nassar’s electronic devices. His lawyers say he “deeply regrets” his crimes.

Olympian McKayla Maroney calls Nassar a “monster” and is urging a judge to set the maximum sentence.
