Someone with that amount of Bitcoin? There is no way they would store on their mobile phone in an exchange or on a samsung phone. This has to be fake. How on earth could a whale let this happen in such a hacker driven environment around the space? I don't believe this.
You have a point though, but, nobody can tell what exactly happened to him as such amount shouldn't have be kept into online wallet. The victim might be those who haven't interested in the knowing of this technology but rather love to associate with the investment involved. We still have many of them till date and when this happened they tend to blame the community. We must learn many things about security in thus regards, the amount of funds are too much to keep online. As you're investing in your portfolios ensure to invest in your knowledge too.
