PURVIS, Mississippi - A former youth gymnastics coach was sentenced to 90 years in federal prison Wednesday for secretly recording young female gymnasts undressing and using the bathroom at a Mississippi gym.

Big picture view: U.S. District Judge Kristi Johnson handed down the maximum possible sentence to Sean Gardner, 39, ordering him to serve 30 years for each of three federal child pornography production charges to which he pleaded guilty.

The sentence is likely to keep Gardner behind bars for the rest of his life.
