A Houston man has been sentenced to more than eight years in prison for trafficking firearms to Colombia.

According to the U.S. Attorney's Office, Patrick Regan smuggled more than 300 firearms to organizations in Colombia that take over and control areas of the country by killing law abiding citizens and legitimate police officers.

The 41-year-old Regan pleaded guilty in January 2012 to conspiracy to make and making a false statement to a federal firearms licensee, dealing in firearms without a license, possession of firearms with obliterated serial numbers, and possession of an unregistered firearm.

In October 2010, the Bureau of Alcohol, Tobacco, and Firearms and Homeland Security Investigations learned that Regan had acquired an unusually large number of firearms and related equipment beginning in October 2009, and had been receiving substantial sums of money from banks in Colombia.

Following completion of the sentence, Regan will have to serve two years of supervised release during which he cannot commit any further crimes and cannot possess a firearm.
