I find it weird that she would wire $55k to gox only to commit suicide when it when down. She must have known risk was fairly high. Either way she went on way too early.
If true, I would then suspect (given human nature) that the money was misappropriated in the first place. Gambling addictions work like that. You double down to pay it back. If the house runs off, you're in a world of hurt and shame.
