se to the exact same facts in his federal case, where an extreme emotional disturbance defense isn't allowed. An emotional disturbance defense is not the same as a not guilty by reason of insanity defense, which would allow a defendant to go to a psychiatric facility instead of prison. Thompson, 50, was killed as he walked to a Manhattan hotel for UnitedHealth Group's annual investor conference. Surveillance video showed a masked gunman shooting him from behind. Police say delay, deny and depose were written on the ammunition, mimicking a phrase used to describe how insurers avoid paying claims. Mangione, an Ivy League graduate from a wealthy Maryland family, was arrested five days later at a McDonald's in Altoona, Pennsylvania, about 230 miles (about 370 kilometers) west of Manhattan. At a hearing last month, Carro ruled that a gun and notebook that prosecutors say link Mangione to the killing can be used as evidence against him. The gun, a 3D-printed pistol, matches the one used to kill Thompson, prosecutors said. The notebook describes wanting to wack a health insurance executive and rebelling against the deadly, greed fueled health insurance cartel.
