Imani Green, the eight year old girl shot dead in Jamaica has been described by her uncle Mitcham Brown as a "quiet, lovely, friendly girl" who had only just begun to grow in confidence.
Mr Brown explained how Imani had sickle cell anaemia as well as a hole in her heart.
He said she would travel to Jamaica every winter with her family because the warm weather helped with her condition.
