  It's the 4th of December 2024.

  Brian Thompson, CEO of United Healthcare, is fatally shot outside a Manhattan hotel.

• 00:11

  Five days later, police arrest a suspect, 26-year-old Luigi Mangione.

• 00:17

  He's charged with murder, to which he later pleads not guilty.

• 00:22

  During a search of Mangione's backpack, police say they find a 3D-printed pistol and silencer.

• 00:29

  Their photo of the alleged murder weapon goes viral on social media,

• 00:34

  and within hours experts identify it as the Chairman One V1.

  It's a partially 3D printed model,

  capable of firing multiple shots without its plastic components breaking.

  The incident highlights how sophisticated 3D printed firearms have become,

  allowing anyone to make an untraceable gun at home.

• 01:26

  for reach.

• 01:27

  I've challenged people offering guns for sale on social media.
