This case is so sad. Andrew was such a cute kid. He was very intelligent and his family seemed to adore him. It's such a waste if he is gone forever.
I am almost exactly a year younger than Andrew.
I was also quiet and didn't have many friends at school.
I was in Year 9 in 2007, and on the first day of the new term, I decided to bunk off school. It was a spur of the moment decision whilst I was getting dressed. I waited for my family to leave, and just stayed at home watching movies and reading Harry Potter fan fiction. I also went to the shop to get chocolate and sweets. I did this 2 or 3 more times until I got caught out.
I was depressed and anxious, and struggled to fit in at school. Maybe Andrew felt something similar. He loved London so maybe he just wanted a spontaneous day to himself to get a break from it all. Unfortunately something went wrong for him somewhere along the lines.
