Canada lottery scam

I am a victim of a Canadian Lotto Scam. They were able to get $14,000
from my accounts including some credit cards. I have contacted the FBI who
stated I am liable for the false check that was sent to me. What are the
steps I can take to handle this? I have no funds in my accounts currently.

Bank involved:

Bridgehampton National Bank
425 County Rd. 39
Southhampton, NY 11968

but according to them someone created the checks using their address and
using one their account numbers that has not been used for awhile.

And yes, I was instructed to send "tax", "insurance", and "customs" fees by
Western Union and some by Moneygram. They gave me a name of a different
person to send it to for each specified amount of "fee".

They skillfully play a psychological game on hope and such, but within 2
days I began to suspect and called the bank, checked further on their
information;

"Winners Trust Finance Inc.
117 UPHill Ave.
St. John, NF, Canada A5C 3X6"
