What broke my heart was how sad his father was when I told him, he said he trusted the son the most.
The question to me here is what resulted to your uncle's son to do that. Are they financially struggling or is it just they do it for fun since they can't be arrested easily from what they've done. The friend of your uncle's son maybe also part of the problem, maybe he is the one that influenced him to commit fraud at that young age.
Now with our digital age, it's very easy for young people to have sccess with smartphones. Even my cousines who are just 5 years old know how to use one so we should really watch them what they are surfing through the internet since those stage, they are very gullible and innocent on many things.
