"Mr. Teixeira’s lawyers described him as compliant — and said he sat on the porch reading a Bible as he waited to be arrested..."

"... but the government painted a starkly different picture. In arguing for his confinement, prosecutors described a panicked effort by Airman Teixeira to cover up his actions as law enforcement closed in.... Investigators found a small arsenal in his bedroom at the house he shared with his mother and stepfather. Inside a gun locker two feet from his bed, law enforcement officials found multiple weapons, including handguns, bolt-action rifles, shotguns, an AK-style high-capacity weapon and a gas mask. F.B.I. special agents also found ammunition, tactical pouches and what appeared to be a silencer-style accessory in his desk drawer.... Prosecutors also made public a series of social media posts from 2022 and 2023 in which Airman Teixeira expressed his desire to kill a 'ton of people' and cull the 'weak minded,' and described what he called an 'assassination van' that would cruise around killing people in a 'crowded urban or suburban environment.'"
