Poaching
Gérard was born around 1985 in the Democratic Republic of the Congo, then moved to the Republic of the Congo in 2008. He began poaching elephants that year in the Nouabalé-Ndoki National Park, the namesake for the nickname “Butcher of Nouablé Ndoki”. He led a group of about 25 poachers, and they poached at least 500 African forest elephants. Gérard's group were connected to an incident in early 2018, where they were caught with 11 poached elephants. Gérard got away, but three members of his group were arrested, and Gérard had an arrest warrant issued on him. Gérard's group were also connected to an indicent on May 31, 2019, where they shot at park rangers and injured two of them.

Prosecutions
Gérard was arrested in May 2018 and was sent jail in Ouésso to await trial. On June 2, 12 days before his trial, he escaped from jail. He was given trial in absentia, and was charged five million CFA franc in damages, and was sentenced to five years in prison.

Gérard was arrested again on July 20, 2019, and was sent back to jail in Ouésso. He attempted to escape, but failed. He was then transferred to jail in Brazzaville.

On August 19, 2020, after a 3-year long investigation, Gérard received a 30-year prison sentence on charges of attempted murder, ivory trading, poaching, and possession of military weapons. He was also required to pay 38 million CFA franc to the rangers he injured. He was the first poacher tried criminally in the Republic of the Congo, as other poachers were tried in civil court, which has maximum sentencing of five years. He also received the longest sentence for a poacher in the Republic of the Congo.
