Three Americans transferred from Congo to US, one arrested in Utah, charged with coup to overthrow government

A criminal complaint unsealed Wednesday in the District of Utah charged four U.S. citizens with conspiring to unlawfully carry out a coup d’état in the Democratic Republic of the Congo (DRC).

Marcel Malanga, 22, Tyler Thompson, 22, Benjamin Zalman-Polun, 37, and Joseph Peter Moesser, 67, are charged with conspiracy to provide material support and resources, conspiracy to use weapons of mass destruction, conspiracy to bomb places of government facilities, and conspiracy to kill or kidnap persons in a foreign country, among other offenses, according to a news release from the U.S. Department of Justice (DOJ).

CONGO COMMUTES 3 AMERICANS' DEATH SENTENCES FOLLOWING COUP ATTEMPT

The men are accused of conducting an armed coup, specifically targeting DRC President Félix Tshisekedi and Deputy Prime Minister for the Economy Vital Kamerhe, attacking both the Palais de la Nation — the official home and principal workplace of the president — and Kamerhe’s private home in Kinshasa, DRC. 

At least six people died during the attack, including two police officers protecting Kamerhe’s home, and at least one innocent civilian. 

The DOJ said the goal of the operation was to murder President Félix Tshisekedi, Kamerhe and others, establish a new government known as the New Zaire, and install leader Christian Malanga, who died during the coup, as the president of the New Zaire.

Marcel Malanga identified himself as the "Chief of Staff of the Zaire army"; Polun was Christian Malanga’s chief of staff; Moesser was the explosives maker, technician and supplier; and Thompson was a soldier, drone specialist and operator, according to the complaint.

Christian Malanga, Marcel Malanga, Thompson, Polun and Moesser allegedly conspired to provide material support and resources including services, training, expert advice or assistance, communication equipment, weapons, explosives, and personnel to the rebel army which was formed to overthrow the DRC government.

The DOJ also accused the men of conspiring to acquire and use weapons of mass destruction during the coup. 

They allegedly planned to use bombs that could be deployed to their targets, including people, private homes and public buildings, via drones. 

In addition, they intended to attach a flamethrower device to a drone and use it as an incendiary device to light people on fire.

Earlier this month, the DRC president commuted Marcel Malanga, Thompson and Polun's death sentences, switching them to life imprisonment.

If convicted, the men face a maximum penalty of up to 15 years in prison for each count of conspiring to provide material support and resources, and up to life in prison for each count of conspiracy to use weapons of mass destruction, conspiracy to bomb places of government facilities, and conspiracy to kill or kidnap persons in a foreign country. 

Malanga and Thompson, if convicted, would also each face a maximum sentence of up to 15 years in prison for each count of taking a firearm out of the U.S. to engage in a felony.

Malanga, Thompson and Polun are expected to make their initial appearances at the federal courthouse in Brooklyn, New York. Moesser is expected to make his initial appearance on April 10 at the federal courthouse in Salt Lake City, Utah.

After their initial appearances in New York, it is expected that Malanga, Thompson and Polun will appear in Salt Lake City for further legal proceedings.

The case is being investigated by the FBI Salt Lake City Field Office, with assistance by the FBI New York Field Office and the FBI’s Legal Attaché Office in Nairobi, Kenya, which oversees the Democratic Republic of Congo.
