Defense Department official Gen. Luis Oliver says it was the second largest cash seizure in Mexican history.
The biggest was in March 2007 when police seized US$207 million linked to a trafficking ring for pseudoephedrine, the main ingredient in methamphetamine.
Oliver says soldiers made the seizure on Sept. 14 at a house in the Pacific coastal state of Sinaloa. They also found documents naming a member of a gang allegedly led by Ismael Zambada, an associate of suspected Sinaloa cartel chief Joaquin Guzman.
Oliver told reporters that soldiers on patrol raided the house after seeing a man hide a gun inside.
