Now MailOnline has traced Ibrahim's mother and she has broken her silence to discuss the case for the first time - and deny her own anti-Swedish bigotry could explain what happened.
Istar Yusuf Nuh, 42, instead insists she would have warmly received Saga into her family as well as the unborn baby son she was carrying when she was killed.
The mother-of-three told us she did not have problems with her son dating a non-Muslim and that Saga's death had robbed her of a grandson she would have loved.
She admitted her son had never brought Saga home and that she was unaware until after she died that she had been in a relationship with her son and was seven months pregnant by him.
She told us: 'I would have been happy if Amin had met a girl and for me it wouldn't matter if she was Swedish or not.
'I would have been happy if he showed me the girl. If Amin had come home and told me that he had got a girl pregnant, I would have been happy to become a grandmother, and especially a young grandmother.
