His motivation was unclear, but Mr Shortland heard from Mr Ncube's fiancee, Sharon Arnott, who said two or three months before his death he revealed his real name "in the context of an emotional discussion''.
"Despite that revelation, he was unable to give reasons why he had not told her earlier,'' Mr Shortland said.
"This was an important demarcation in their relationship, and as Ms Arnott has said under oath, she felt that he was being honest and believed him.
``Despite her attempts to ask why he chose to make this revelation now, he would only answer that he couldn't go into it and was unable to tell her.''
Had Mr Mncube not died the Department of Immigration, would probably have had a prima facie case to charge him, Mr Shortland said.
