NEW HAVEN — A New York man packed three vans with sophisticated explosives and was in the advanced stages of an apparent plot to kill his estranged wife when he was caught in Connecticut with a disguise, federal authorities say. Yung Tang, 39, was arrested a year ago after he was found in a parking lot in Wallingford asleep in a vehicle with explosives and a fake mustache and makeup, authorities said . . .
Two more vans were later found in Brooklyn, N.Y. . . .
In court papers filed this week, prosecutors called for Tang, a citizen of China, to be sent to prison for 20 years when he is sentenced Feb. 12.
The vans included homemade explosive devices connected to remote detonators, firearm silencers and jugs filled with sulfuric acid, a known agent for accelerating the decomposition of a body, authorities said . . .
Tang, a citizen of China last residing in Greenwood Lake, N.Y., who has been detained since his arrest, was already charged with a 2002 pipe bomb attack in New York that blew off part of a man’s leg.
The bombing victim was Tang’s commercial tenant and was behind in his rent, attorneys said . . .
