NEW YORK (AP) - A man admitted knowing how to manufacture a bomb-making explosive discovered in his Manhattan apartment and had told his live-in girlfriend he was eager to add to his gun collection in the wake of the Newtown school shootings, according to court papers made public on Tuesday.
Aaron Greene told investigators "he made the HMTD found in his apartment" last month, the papers say. "He discussed technical details about its composition and manufacture."
The girlfriend, Morgan Gliedman, described how after news of the massacre in Connecticut that left 20 children dead, Greene "told her they ought to go buy more guns before the law is changed," the papers add.
HMTD stands for hexamethylene triperoxide diamine, a highly explosive ingredient used in bomb-making. Aside from 7 grams of the substance, police say they also recovered two shotguns, ammo and papers titled "The Terrorist Encyclopedia" and "Deadly Homemade Weapons" in their Greenwich Village apartment.
The discovery late last month caused a scare that resulted in the arrest of both Greene and Gliedman- daughter of a prominent New York City physician- late last month on weapons possession charges. Authorities have described the pair as heroin addicts.
At the time of her arrest, Gliedman, 27, "stated she had not realized the extent of defendant Greene's collection of weapons and ammunition," the court papers say.
The alleged statements were disclosed on Tuesday during a court appearance where Greene, 31, pleaded not guilty.
Gliedman, who was nine months pregnant at the time of her arrest, went into labor while in custody and gave birth to a daughter, Melanie, on Dec. 31. She was released on bail earlier this month and ordered to complete a 30-day drug rehab program.
Since the arrests, police alleged Green told acquaintances late last year that he planned to blow up the Washington Square Park arch. Also uncovered were undated letters that he wrote, including one with the words "kill them all" and signed with a Nazi SS lightning bolt symbol still used by neo-Nazi groups, police said.
