Federal security spokesman Alejandra Sota says the federal forces will reinforce operational and intelligence work in the state of Veracruz. She doesn't say how many troops and officers are being sent.
Sota says Veracruz's government has asked federal prosecutors to take over the body-dumping investigation.
Authorities have said the victims were linked to the Zetas drug cartel. The killers are believed to be from the New Generation gang, a group that is associated with the Sinaloa cartel.
Sota announced the deployment Wednesday.
