At the same conference, a panel devoted to Jaynes was also held, with John Limber ( University of New Hampshire ), Marcel Kuijsten, John Hainly ( Southern University ), Scott Greer ( University of Prince Edward Island ), and Brian J. McVeigh presenting relevant research.

Within 90 minutes of the explosion, Timothy McVeigh was stopped by Oklahoma State Trooper Charlie Hanger for driving without a license plate and arrested for unlawfully carrying a weapon.

Forensic evidence quickly linked McVeigh and Terry Nichols to the attack ; Nichols was arrested, and within days both were charged.

McVeigh, an American militia movement sympathizer who was a Gulf War veteran, had detonated an explosive-filled Ryder truck parked in front of the building.

McVeigh was executed by lethal injection on June 11, 2001, and Nichols was sentenced to life in prison.

Michael and Lori Fortier testified against McVeigh and Nichols ; Michael was sentenced to 12 years in prison for failing to warn the U. S. government, and Lori received immunity from prosecution in exchange for her testimony.

McVeigh wore a printed T-shirt with the motto of the Commonwealth of Virginia, Sic semper tyrannis (" Thus always to tyrants ", which was shouted by John Wilkes Booth immediately after the assassination of Abraham Lincoln ) and " The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants " ( from Thomas Jefferson ).

McVeigh was arrested within 90 minutes of the explosion, as he was traveling north on Interstate 35 near Perry in Noble County, Oklahoma.

After booking McVeigh, Hanger searched his police car and found a business card McVeigh had hidden while he was handcuffed.

McVeigh's sister Jennifer was accused of illegally mailing bullets to McVeigh, but she was granted immunity in exchange for testifying against him.

McVeigh later stated that he was unaware of the day-care center when choosing the building as a target, and if he had known "... it might have given me pause to switch targets.

McVeigh was represented by a defense counsel team of six principal attorneys led by Stephen Jones.

According to law professor Douglas O. Linder, McVeigh wanted Jones to present a " necessity defense "— which would argue that he was in " imminent danger " from the government ( that his bombing was intended to prevent future crimes by the government, such as the Waco and Ruby Ridge incidents ).

Jones also believed that McVeigh was part of a larger conspiracy, and sought to present him as " the designated patsy ", but McVeigh disagreed with Jones arguing that rationale for his defense.

They included a confession said to have been inadvertently included on a computer disk that was given to the press, which McVeigh believed seriously compromised his chances of getting a fair trial.

On June 2, 1997, McVeigh was found guilty on eleven counts of murder and conspiracy.

Although the defense argued for a reduced sentence of life imprisonment, McVeigh was sentenced to death.

In addition to arguing that the bombing could not have been carried out by two men alone, Jones also attempted to create reasonable doubt by arguing that no one had seen McVeigh near the scene of the crime, and that the investigation into the bombing had lasted only two weeks.

McVeigh also wrote to Congressman John J. LaFalce, complaining about the arrest of a woman for carrying mace:

The government also imposed new firearms restrictions in 1994 that McVeigh believed threatened his livelihood.

Around this time, McVeigh and Nichols also began making bulk purchases of ammonium nitrate, an agricultural fertilizer, for resale to survivalists, since rumors were circulating that the government was preparing to ban it.

McVeigh also wrote a letter of recruitment to a customer named Steve Colbern:

McVeigh noted that he had no knowledge that the federal offices also ran a daycare center on the second floor of the building, and noted that he might have chosen a different target if he had known about the daycare center.

McVeigh was wearing a T-shirt at that time with a picture of Abraham Lincoln and the motto: sic semper tyrannis (' Thus always to tyrants '), the state motto of Virginia and also the words shouted by John Wilkes Booth after he shot Lincoln.

Individuals, such as Timothy McVeigh, may also engage in terrorist acts such as the Oklahoma City bombing.

McVeigh and Nichols also robbed an Arkansas gun dealer who had befriended them at various gun shows.

Investigators also combed the Decker, Michigan, farm of James Nichols where Terry Nichols and McVeigh had stayed intermittently in the months preceding the bombing.

She also testified that Nichols traveled to Oklahoma City three days before the bombing, supporting the prosecution's contention that Nichols helped McVeigh station a getaway car near the Murrah building.

Marife also failed to give Nichols an alibi for April 18, 1995, the day the prosecution said Nichols helped McVeigh assemble the truck bomb.

Fortier also testified that McVeigh and Nichols stole cord and blasting caps from a rock quarry, and that Nichols robbed a gun collector to obtain money for the plot.

Nichols also said that in 1995 McVeigh told him that FBI official Larry Potts, who had supervised the Ruby Ridge and Waco operations, had directed McVeigh to blow up a government building.

Jail records are also sometimes used ; for instance, after the U. S. Government determined that Timothy McVeigh had perpetrated the Oklahoma City Bombing, he was found in a local jail.

The Turner Diaries has also been described as the inspiration for the Oklahoma City bombing on April 19, 1995, due to the similarity to the book's account of the destruction of a government building in Washington, D. C., and the fact that Timothy McVeigh was an avid reader of The Turner Diaries.

Ray McVeigh also joined the band as a second guitarist.

Lea McGown, manager of the local Dreamland Hotel, identified the sketch as Timothy McVeigh.

" Three days later, while still in jail, McVeigh was identified as the subject of the nationwide manhunt.

Motivated by his hatred of the federal government and angered by what he perceived as its mishandling of the Waco Siege ( 1993 ) and the Ruby Ridge incident ( 1992 ), McVeigh timed his attack to coincide with the second anniversary of the deadly fire that ended the siege at Waco.

McVeigh wrote a letter to Moore in which he claimed that the robbery had been committed by government agents.

As he drove toward the Murrah Federal Building in the Ryder truck, McVeigh carried with him an envelope containing pages from The Turner Diaries — a fictional account of white supremacists who ignite a revolution by blowing up the FBI headquarters at 9: 15 one morning using a truck bomb.

After President George W. Bush approved the execution ( McVeigh was a federal inmate and federal law dictates that the President must approve the execution of federal prisoners ), he was executed by lethal injection at the Federal Correctional Complex, Terre Haute in Terre Haute, Indiana, on June 11.

Additional theories claim the bombing was done by the government to frame the militia movement or to provide the impetus for new antiterrorism legislation while using McVeigh as a scapegoat.

While in high school, McVeigh became interested in computers and hacked into government computer systems on his Commodore 64, under a handle – " The Wanderer " – borrowed from the song by Dion DiMucci.

McVeigh was introduced to firearms by his grandfather, and told people he wanted to be a gun shop owner and sometimes took firearms to school to impress his classmates.

McVeigh was reprimanded by the military for purchasing a " White Power " T-shirt at a Ku Klux Klan protest against black servicemen who wore what he viewed as " Black Power " T-shirts around the army base.

McVeigh dissociated himself from his boyhood friend, Steve Hodge, by sending a 23-page farewell letter to him.

Shortly after the bombing, while driving on I-35 in Noble County, near Perry, Oklahoma, McVeigh was stopped by Oklahoma State Trooper Charles J. Hanger from Pawnee, Oklahoma.

On August 10, 1995, McVeigh was indicted on 11 federal counts, including conspiracy to use a weapon of mass destruction, use of a weapon of mass destruction, destruction by explosives and eight counts of first-degree murder.

McVeigh tried to calm his mother by saying, " Think of it this way.
