(CNN) -- A judge sentenced a former Peace Corps volunteer to 15 years in prison for abusing girls under the age of 6 in South Africa while he was a volunteer there, federal officials said. The sentencing was announced Thursday in a statement from U.S. Immigration and Customs Enforcement. Jesse Osmun, 33, of Milford, Connecticut, joined the Peace Corps in 2010 and worked in a nongovernmental organization's AIDS center for children whose families had suffered or died from the disease, his attorney, Richard Meehan, Jr., told CNN Thursday. Osmun volunteered as a Web designer for the center and worked with older children in a "scout" program.
