I feel I have more understanding of Sharmeena and the impact of her mother's death on her and her family - she was clearly a very vulnerable young person at that time. I don't think a girl as vulnerable as Sharmeena was in a position to groom another, but their relationship might highlight the dynamics of freindships and the power of groups in influencing us. In that respect, it might not make a great deal of sense to look at Shamina in isolaton, however, I don't think we have much information on her to help beyond the most superficial understanding. Because of her age and what we know about radicalisation and the dynamics of grooming, we might assume that the latter occurred, but we have no evidence of how it took place and what in particular might have made Shamina Begum more vulnerable to it than other adolescent girls. If her history is out there, I haven't come across it, and I have looked.
As an example, in work, if I make a referral to the CSE service, I need evidence about makes the child vulnerable, their early childhood, their relationships with parents/carers/other adults, is there alcohol or drug use at home, or DV, difficulties at school and with peers, are there mental health difficulties, developmental trauma, fetal alcohol syndrome, what services have been and are involved, as well as dates/times of incidents and names were possible. This kind of information is missing, I don't feel we know anything about her at all.
