Michel Guinot was an French arms dealer.
Realizing San'ko wasn't paying her enough money, Anna Espinosa contacted Guinot to sell him a chemical bomb. They met in Venice, Italy and discussed their terms, beginning the transaction. However, Sydney and Vaughn overlooked the deal and wound up interrupting the deal. Guinot tried to escape with the bomb, but Vaughn tackled him from behind and knocked him out, where he was presumably taken into custody afterwards.
