Local authorities say American Felix Batista was in Mexico to give talks and offer advice against kidnapping. The former U.S. army officer sometimes serves as a negotiator with kidnappers.
Batista is a consultant for the Houston, Texas-based security firm ASI Global LLC.
ASI Global President Charlie LeBlanc says Batista was abducted on Dec. 10 in Saltillo, the capital of Coahuila.
LeBlanc said Monday that the FBI and Mexican police are working on the case, but would not say whether any ransom demand has been received.
