On a Tuesday in early September, Jeriah Mast stood before Judge Donald C. Nugent in a federal courtroom in Cleveland, entering a guilty plea that could keep him behind bars for decades. The 45-year-old former missionary admitted to sexually abusing two boys in Haiti, crimes that spanned years of his work with an Ohio-based religious organization. The plea agreement, reached with federal prosecutors, sets an expected sentence between 25 and 33 years, though the judge will have the final say at the December 15 sentencing hearing.

Mast, a resident of Millersburg, Ohio, had made multiple trips to Haiti for mission work from 2002 through 2019. He was affiliated with Christian Aid Ministries, which coordinates humanitarian and missionary activities supported by Amish, conservative Mennonite, and related Anabaptist church groups. Mast himself belonged to a church within that movement. His case has become a flashpoint for broader discussions about sexual abuse in these insular, plain-dressing communities, where forgiveness is often prioritized over legal accountability.

According to court records, Mast told police in 2019 that he had molested more than 30 boys in Haiti and four children in Ohio. That year, he was sentenced in Holmes County, Ohio, to nine years in state prison for gross sexual imposition involving two boys. But in October 2025, retired Judge Edward Emmett O'Farrell of Tuscarawas County granted Mast an early release from state prison, citing his exemplary record behind bars and, most importantly, what the judge described as Mast's stated and demonstrated remorse for the emotional and psychological pain he caused his victims and their families.

Federal authorities had been investigating Mast's actions in Haiti for years, but the probe remained largely dormant while he served his state sentence. Once they learned of his early release, prosecutors accelerated their investigation. Mast was arrested on federal charges last November and formally indicted in December on four counts of engaging in illicit sexual conduct in a foreign place. The indictment alleged he abused four boys in Haiti — one in 2004, one in 2007, and two in 2011.

Under the plea agreement, Mast pleaded guilty to charges involving a 2004 incident and one of the 2011 incidents, each involving a minor between 12 and 16 years old. Prosecutors agreed to move to dismiss the remaining two charges, though Mast admitted to the factual basis for those as well. The charges were brought under a U.S. law that prohibits citizens from engaging in any illicit sexual conduct with another person overseas.

Mast's legal team had challenged the constitutionality of that law, filing a motion in May to have the charges dismissed on the grounds that Congress overstepped its authority to regulate citizens' conduct abroad. The court denied the motion in August. The plea agreement allows Mast to appeal that ruling.

Assistant Attorney General A. Tysen Duva of the Justice Department's Criminal Division called Mast's conduct a profound betrayal of trust, noting that a person entrusted with missionary work exploited that position to prey on vulnerable children. He said the guilty plea is an important step toward justice for the many victims harmed by Mast's actions.

The case has also drawn attention to Christian Aid Ministries, which became the subject of scrutiny in 2019 when it placed two managers on leave after revelations that they knew as early as 2013 that Mast had confessed to sexual misconduct yet kept him on the job. CAM's work in Haiti made international headlines in 2021 when 17 of its missionaries and their children were kidnapped by a gang. They were freed later that year, some after ransoms were paid, while most escaped.

Holmes County, where Christian Aid Ministries is based, is home to one of the largest Amish settlements in the United States and also has a significant Mennonite population. The community continues to grapple with the fallout from Mast's crimes and the systemic issues that allowed them to persist for years.
