Land O’Lakes Woman Charged with Assisting After the Fact and Evidence Tampering Related to an Attempt to Detonate an Improvised Explosive Device at MacDill Air Force Base

Tampa, Florida - Ann Mary Zheng (27, Land O'Lakes) has been charged by indictment with assisting after the fact related to her brother, Alen Zheng, placing an improvised explosive device at the MacDill Air Force Base Visitor's Center in Tampa and evidence tampering. If convicted on all counts, Ann Mary Zheng faces a maximum penalty of 30 years in federal prison. The indictment also notifies Ann Mary Zheng that the United States is seeking an order of forfeiture in the amount of $5,000, the proceeds of the charged criminal conduct. United States Attorney Gregory W. Kehoe made the announcement.

According to the indictment, Ann Mary Zheng, knowing that her brother, Alen Zheng, had attempted to damage government property by fire or explosion, assisted him in order to hinder and prevent his apprehension, trial, and punishment. The indictment also charges Ann Mary Zheng with corruptly altering, destroying, mutilating, and concealing a 2010 black Mercedes-Benz GLK 350 with the intent to impair its integrity and availability for use in the federal prosecution of Alen Zheng.

An indictment is merely a formal charge that a defendant has committed one or more violations of federal criminal law, and every defendant is presumed innocent unless, and until, proven guilty.

This case was investigated by the Joint Terrorism Task Force. It will be prosecuted by Assistant United States Attorneys Lauren Stoia and David P. Sullivan.
