Brother, Sister Indicted in Alleged IED Plot At Florida Air Force Base Tied to Iran War; 1 Suspect in China
26th March 2026
A brother and sister have been indicted after authorities say one of them planted a potentially deadly explosive device outside MacDill Air Force Base in Florida — then fled to China, while their mother is now in ICE custody after allegedly telling investigators her son confessed to the plot.
The FBI said Alen Zheng, who is believed to have planted the device, is currently in China. He is facing charges of attempted damage to government property by fire or explosion, unlawful making of a destructive device and possession of an unregistered destructive device, which carry a potential sentence of up to 40 years in prison.
FBI Tampa also arrested his sister, Ann Mary Zheng, who is charged with accessory after the fact and tampering with evidence, facing up to 30 years in prison.
She is accused of hiding or damaging a 2010 Mercedes-Benz to prevent its use in legal proceedings, court documents show.
Prosecutors allege that on March 11, the day after the bomb was planted, the siblings attempted to cover their tracks by selling the vehicle to car dealer CarMax. Despite being vacuumed and cleaned, investigators later discovered trace explosive residue inside the vehicle.
