(WTNH) – The daughter of an Illinois woman who passed away last month received an interesting message from Chase Bank, “Your checking account has a balance of negative $99,999,999,545.90.”

Sheila Henderson was listed on her deceased mother’s account and had called the bank to check the balance in order to pay off some funeral expenses. She was shocked when she heard the astonishing number.

Henderson told WABC New York: “I called my brother to listen to it and the first thing he said, ‘You have been hiding all this money from me. Why did you do this? Come on. Let’s go.’ I was like, ‘No, it says it is a negative amount on it,” Henderson said.

Since the account was overdrawn by $99 billion, Henderson was concerned about being responsible for the large sum of money. Chase Bank has told WABC that they’re investigating and will work with Ms. Henderson on fixing the issue; which she calls a “$99 billion mistake”.
