I get what you're saying, but quite literally they were pocketing the money. It's, allegedly, just sitting in accounts owned by Jirard's family's charity while they lie about "every cent" of it being donated. I agree that the connotation of saying "pocketed" is more that they personally took it, but it was still pocketed instead of being donated.
I'm very interested to know what happened to any interest on those accounts, how much of it was expensed to run the fundraising events, and, of course, whether the money is even still there.
