OKLAHOMA CITY » A federal judge is scheduled to hand down a sentence to a former missionary from Oklahoma who was found guilty of sexually abusing children at an orphanage in Kenya.

Sentencing is scheduled Monday for Matthew Lane Durham. The 21-year-old Edmond man faces up to 30 years in prison on each of four counts of engaging in illicit sexual conduct in foreign places.

A 12-member jury convicted Durham in June on a total of seven counts, but U.S. District Judge David L. Russell acquitted Durham on three of the counts in January.

Prosecutors alleged Durham targeted orphans while volunteering at the Upendo Children’s Home in Nairobi between April and June 2014. The four counts Durham was convicted of involved three girls and a boy ranging in age from 5 to 14.
