The investigative journalist and assistant editor at the Catholic run Mission Press, in the northern town of Ndola, was found dead under mysterious circumstances. His body was found floating on a lake in the rural district of Masaiti, exactly ten days after he had gone missing. He was hastily buried by the police at Kantulomba Cemetery in Ndola in the absence of his family, even though there were some identification documents that were found on him. Humphery went missing on 22 September, a day before he was due to travel to Germany for a journalism training programme.
