A retired St. Louis police lieutenant has been sentenced to five years in prison for possessing child pornography.

Sixty-six-year-old-old Ronald Oldani was sentenced Wednesday in U.S. District Court. He pleaded guilty in September to two counts of possession of child pornography.

Police found more than 100 multimedia files containing child pornography on Oldani's computer. He served as a St. Louis officer for 30 years, retiring in 2009.
