A defense attorney for a 20-year-old Oklahoma man accused of sexually abusing children at a Kenyan orphanage is scheduled to begin presenting evidence to jurors.

Testimony resumes Tuesday in the trial of Matthew Lane Durham. He faces 17 charges, including aggravated sexual abuse and engaging in illicit sexual conduct in foreign places. Durham has pleaded not guilty. He faces up to life in prison if convicted.

Durham's defense attorney, Stephen Jones, is scheduled to begin questioning witnesses on Durham's behalf. Federal prosecutors wrapped up their case Monday after questioning 24 witnesses, including five children.

Durham is accused of molesting children between April and June 2014, while he was a volunteer at the Upendo Children's Home in Nairobi, Kenya.
