 Wilson was 27 years old.In the weeks following the killings, Charlotte's mother and her younger brother, Richard, made public appeals to the British government to investigate the incident and to treat it as a War Crime, a move which met with limited success.Richard continued his enquiries personally, however, and via the Human Rights Watch organisation and various contacts he had made in Rwanda and Burundi, he established that the FNL, under the leadership of Albert Sibomana, were responsible for the killing.
