Terry Nichols is an American man known for his involvement in the 1995 Oklahoma City bombing, one of the deadliest acts of domestic terrorism in U.S. history. Alongside Timothy McVeigh, Nichols helped plan and execute the attack, which resulted in the deaths of 168 people and injured over 600 others. He was arrested shortly after the bombing and faced multiple charges. In 1997, Nichols was convicted of conspiracy to use a weapon of mass destruction and was sentenced to life in prison without the possibility of parole. In 2000, he was tried again for murder in state court and received 168 additional life sentences, one for each victim of the bombing.
