What company would allow child labor? No one is going to let a 14 year old code games for them or something. He wouldn't have had an NI at the time so they wouldn't make promsies like that. My first coding job was at 16 and even then I had to get my contract notorized and it was a whole process. Also, Oxford to Doncaster is like a 3hr and 20min train journey.
Most people are just not involved in most things. Theyre involved in some, but with community as big and full of so many different people as schools are its just impossible to learn, have some hobbies, some private life, keep up with friends and/or some other activities like sports and so on AND ALSO know whats going on with dozens on dozens of people around. Not that much hiding is really needed usually.
Perfetc GPA and life of a party, and girlfriend, and friends, and volunteering. Well, I wouldnt say that sounds normal. Thats what you want to have in so called perfect scenario but realistically barely anyone can and hard to find anyone who would have ALL that and like 10, 20, 30 years later say it was all tiring but awesome and fun. Usually not how it goes unless theyre politicians but then they want to keep that picture perfect still.
We do have no idea what was going on with Andrew, but he wasnt an alien for unknown planet but a young boy from UK. People are not that different from each other. Many different factors so its rarely possible to guess right what was going on having just a very basic description of events but it is possible to get general idea.
Almost 20 years, parents havent figured it out. Sister havent figured it out. Investigators havent figured it out.
Nothing seems to back up the theories about Andrew having some secret life.
He may have, but if nothing like that was tracked then its safe to assume that its LESS likely that he had some big secrets than that he hasnt. Wasnt a secret that he liked London a lot. Its the way and the time he went there whats baffling. But there are hints that something at least unpleasant was going on. Cause he wasnt all happy and excited in the morning, it wasnt the normal morning for him. He anticipated something stressful.
Another kinda sure thing is that on the footage all people are looking same direction, each frame. Theyre just walking. Andrew is looking around. May not mean anything but again - more likely that he was looking for someone than that he suddenly became very interested in the surroundings... or that he was nervous cause he didnt get where he planned yet.
Another reason for not buying a returning ticket could be not having a plan to go back via London.
If the goal was to go to Oxford for example, then catching a train to London and then bus to Oxford could be the fastest way to get there. No reason to go back to London if then he could just catch a train from Oxford to Doncaster and theoretically be home for dinner.
*that Oxford is very random, just a possible reason for not buying return ticket apart from assuming on getting ride back home from London.
May be nothing to figure out. If the reason was known only to the Andrew and the person he went to meet/visit at London (or elsewhere) but that person hasnt groomed him online but met somewhere before there is no way to guess or track it down.
Lets say it wasnt some mysterious "girl" he wanted to met, nor a music concert. What if it was work related?
Yeah, sure, Andrew was 14. Old enough to hear that hes very smart and can help develop this awesome new game or build a program, work on computers, whatever. Visit me in Oxford someday (or on this specific day) I'll explain all the details to you, and aim gonna give you a laptop to work on and were gonna make it. Dont tell anyone about this cause they may steal our idea!
That story would be much smoother if I spend more than 3 mins typing that. Just a general concept. Secret not cause working on a game (for example) would be a bad thing. But parents may be worried that kid is working instead of focusing fully on school to get best grades possible. And its easy to make such a thing worth to keep secret until its done. Game, program, service, website, something like that. Then the motive would be to invest in his future.
Could we say that sort of scenario was impossible? Dont think we can. But we cant also rule out something as "trivial" as feeling bad and wanting to go and visit favorite place while not thinking about anything but to get there and have some piece of mind for an hour or two, THEN deal with the consequences and explanations and getting abducted by random.
But probability says nah. Much more likely that sudden trip which ended in disappearance was connected than that it wasnt. And almost certainly it made sense for Andrew.
To me, JMO, figuring out what could possibly make a person like Andrew take these actions that we know he did (so skipping school, taking all the money from the account but not all the money available, buying one way ticket to London, not leaving any info for parents) would offer a hint. Not a oh yeah, jackpot, Andrew must be thinking/planning same thing. But a hint.
At this point even a hint like that could be useful.
