Deeply upsetting piece of news, as is any suffering of children at the hands of adults or even an older child. As you say Maw too much information for the general public. How awful to sit on the jury of such a case, I'm sure it would haunt you forever.
There is such an ambiguity around "age" at the moment, specifically with the Shamima Begum debacle and the fact that she was 15 when she travelled to Syria and in particular as there are those pushing for the voting age to be reduced to 16, but in the eyes of the law 16 is still a child. I suppose age is quite arbitrary if one is a psychopath or have developmental issues. Under normal circumstances 16 is old enough to understand right from wrong and cause and effect.
Poor little Alesha, she looked such a happy soul, I believe she loved going to Bute to stay with her father and grandparents how awful for them and of course her poor mother.
The boy did seem to be under the influence of drugs and I believe pornography came up at some stage, both very pernicious imo.
