Terry Nichols was born April 1, 1955, in Michigan. He served in the U.S. Army and later worked as a military surplus dealer in Kansas before becoming entangled with Timothy McVeigh in the early 1990s. On April 19, 1995, a Ryder truck bomb detonated outside the Alfred P. Murrah Federal Building in Oklahoma City, killing 168 people and injuring more than 500.
Investigators quickly identified McVeigh and Nichols as suspects. McVeigh was arrested within 90 minutes of the bombing; Nichols was taken into custody two days later at his mother's home in Michigan.
The prosecution argued that Nichols had helped McVeigh acquire materials for the bomb and had been present when it was assembled. Michael Fortier, a friend who had been told of the plan in advance, testified for the government. He stated that Nichols had helped obtain materials and was present during part of the preparation. Nichols maintained he was unaware of the attack.
