This haunted me terribly back then, it continues to haunt me now. Andrew and myself are exactly the same age - I remember what it was like being a teenager in 2007, secretly exploring dark places and talking to strangers on the internet (pre-smartphones and social media as we know it), taking reckless train journeys to risky locations with friends without telling parents etc etc.
Revisiting this case has thrown me into a total obsession with it and all the possibilities of what happened... (if you also get obsessed with unsolved true crime, there is a very active Reddit page dedicated to Andrew Gosden, but beware getting stuck deep, deep, deep in a worm hole for several days haha)
I'm inclined to believe that he had every intention of returning home to Doncaster, and was either:
- abducted for the purposes of sexual exploitation or trafficking, coming into contact with some opportunistic, nefarious person(s) shortly after arriving in London
- lured to London by someone that he had somehow met and been groomed by, either in-person or online (they claim that no digital evidence of this was found, but I'm convinced that it was much easier to leave no digital trace in 2007.)
Each these explanations and their likely circumstances and outcomes are horrific to consider - but they seem more plausible than the 'runs away to start a new life' or suicide theories. Someone else wanted him gone, and they wanted him gone without a trace.
In any case, my heart breaks for this poor little fella - he seemed such a gentle, innocent, typical teenager striking out for some independent adventure. Unfortunately, the adventure went disastrously wrong. I like to think, if anything, that he did make it through the day in London and had the best time of his life - buying his new PSP console, eating pizza, browsing alternative band merch, maybe attending an event he'd had his eye on, doing all the fun things that a teenage boy would want to do playing truant in the Big Smoke.
(One other interesting speculation is that somehow he did make it back to Doncaster and in fact was abducted by a local, who he may well have met in-person before. Someone on the Reddit raised an imprisoned Doncaster-based paedophile called N. Powers, who targeted vulnerable boys to abuse. He's serving a 14 year prison sentence now, but was active during the time that Andrew disappeared.)
