US Citizen Accused of Planting Bomb at Florida Airbase Flees to China
Authorities are searching for a US citizen who allegedly planted an explosive device at a critical military installation in Florida before fleeing to China. The incident has raised significant security concerns at MacDill Air Force Base, which houses the headquarters of US Central Command overseeing operations in Iran and other regions.
Week-Long Security Breach at Military Facility
According to federal indictments unsealed this week, Alen Zheng is accused of placing a destructive device at the visitors center of MacDill Air Force Base on March 10. After allegedly planting the bomb, Zheng reportedly called 911 to alert officials about the threat.
Investigators conducted searches but failed to locate the device for nearly seven days, during which time the explosive remained undetected at one of America's most strategically important military facilities. The delay in discovery has prompted questions about security protocols at the base.
Sibling Involvement and International Escape
Court documents reveal that Zheng's sister, Ann Mary Zheng, has been charged with assisting her brother's escape. Both siblings are US citizens who allegedly traveled to China on March 12, just two days after the bomb was planted.
While Alen Zheng remains at large in China, his sister was arrested upon her return to the United States and arraigned in a Florida federal court on Thursday. The case highlights the challenges of international law enforcement cooperation between countries without formal extradition treaties.
Evidence Recovery and Investigation Details
Investigators finally discovered the undetonated explosive device on March 16, four days after the Zhengs had already left the country. Through forensic analysis, authorities traced the 911 call to Alen Zheng and located the vehicle used in the alleged bombing at a used car dealership.
Despite the vehicle having been thoroughly cleaned and vacuumed, forensic experts found residue matching the explosive material, according to statements from the US Attorney for the Middle District of Florida. The FBI has taken lead on the investigation, which continues to develop.
Legal Charges and Diplomatic Complications
Alen Zheng faces three serious federal charges:
- Attempted damage to government property by fire or explosion
- Unlawful manufacturing of a destructive device
- Possession of an unregistered destructive device
His sister has been charged with aiding her brother's evasion of arrest by facilitating his travel to China and selling the vehicle allegedly used in the bombing plot. The case presents diplomatic challenges since the United States lacks an official extradition treaty with China, though both nations can negotiate on specific cases.
It remains unclear whether the Zheng siblings hold dual citizenship with China, which could further complicate legal proceedings. The incident has drawn attention to security vulnerabilities at military installations and the complexities of prosecuting cross-border crimes involving American citizens abroad.
