Three Men Sentenced for Providing Material Support to Separatists in Cameroon

KANSAS CITY, Mo. - Three individuals have been sentenced in federal court for their roles in a conspiracy to provide material support or resources to kill, kidnap, and maim persons and use weapons of mass destruction (WMDs) in a foreign country. The defendants conspired to provide funds and equipment to separatist fighters in Cameroon to allow them to construct and use IEDs against various targets in the Northwest Region of Cameroon.

Francis Chenyi, Sr., 52, of Saint Paul, Minn. and Lah Nestor Langmi, 49, of Buffalo, N.Y., both citizens of Cameroon, were sentenced to 180 months each in federal prison, followed by three years of supervised release.

Claude Ngenevu Chi, 43, of Kansas City, Mo., was sentenced to 63 months, followed by three years of supervised release.

Previously, Chenyi and Langmi, both of whom are U.S. citizens of Cameroonian origin, were found guilty after a federal jury trial of one count of a conspiracy to provide material support or resources intended to be used to carry out conspiracies to kill, kidnap, and maim persons in a foreign country and to use a WMD outside the United States. Chenyi and Langmi were also found guilty of one count of being involved in an international money laundering conspiracy that transferred funds from the United States to Cameroon to promote conspiracies to kill, kidnap, and maim and use WMDs abroad. Additionally, Chenyi was convicted of conspiring to provide material support and resources to use a WMD abroad.

Chi previously pleaded guilty to one count of conspiring to provide material support and resources to use WMDs abroad.

According to court documents and evidence from trial, Langmi sent an audio message to separatist fighters requesting they kidnap a traditional leader in Cameroon. Following a battle with Cameroonian forces, separatists took the traditional leader along with the Catholic Cardinal Christian Tumi, who was traveling with the traditional leader, from their vehicles. Following the kidnapping, Chenyi, provided the interrogation questions to be asked of the traditional leader and the Cardinal and approved the transferring of funds through peer-to-peer transactions to the separatist fighters in Cameroon to further the kidnapping.

Chenyi was involved in ransom payments by individuals outside of Cameroon for the release of family members taken in Cameroon and communicated with Langmi about these payments. Multiple instances occurred in which co-conspirators, including Langmi, requested funds to purchase IEDs or components of IEDs for construction and use in Cameroon that were approved and funded by Chenyi. Chenyi also coordinated with individuals in Cameroon to ensure separatist fighters he supported obtained training on IED use. The defendants corresponded with co-conspirators in Cameroon to coordinate development, payment for, and logistical support toward IED use upon targets in Cameroon.

Around Dec. 3, 2020, Chenyi was requested to provide funds for construction of multiple IEDs to be used in connection with efforts to enforce a lockdown of an area before an upcoming election. Chenyi, along with Chi, agreed to provide funds for the IEDs' construction and Chenyi coordinated the transfer of funds from the United States through peer-to-peer transactions to the separatist fighters in Cameroon.

Langmi coordinated with, and provided funds to, an unindicted co-conspirator to develop IEDs and rocket-propelled grenades (RPGs) in Cameroon and kept Chenyi apprised of the IED and RPG development. Langmi also attempted to coordinate attacks near the 2021 African Cup of Nations soccer tournament hosted in Cameroon, as well as various cities throughout the Northwest Region in the spring of 2022.

This case is being prosecuted by Assistant U.S. Attorneys Sean T. Foley and Joseph M. Marquez for the Western District of Missouri, with the assistance of the Justice Department's National Security Division. The case was investigated by the Federal Bureau of Investigation-Kansas City Field Office.
