I’m not sure that discussing these details is productive, and many people are triggered by this kind of detailed talk about suicide. If Richard did take his own life, we will probably find out eventually.
IMO, parents have good instincts about what their kids are up to. If both his mom and dad saw signs that he was being groomed, that seems like a strong lead.
I haven’t been following every page of this thread so apologies if it’s already been discussed, but it could also be that Richard had a mental health break - leaving his money at home, and taking both a bus and a taxi, could be signs of disordered thinking and/or paranoia. I have a family member this happened to and luckily she was rescued before anything happened. Whatever the case is, he is a vulnerable person and 10 days missing is a long time.
