Dr. Maserati said:You're right this isn't hard, so it is odd that you keep getting it wrong.
You say the fund was kept in a Cyclismas bank account and that they (I assume Lesli & Aaron) had a duty that the "money was properly handed".
Which is exactly what Leslie did, she checked the account to find some funds moved, her request for further info appears to have been ignored so she contacted Kimmage and contacted a lawyer to get access to the info.
If I take five thousand from you and promise to pay that money to another person, and my brother then steals all that money from me, I'm not going to be able to walk away from my obligation to you.
That's about as over-simplified as I can make it for you.
