INDIANAPOLIS (AP) — In the final hour before Timothy McVeigh's scheduled execution Monday morning, more than 25 people will be escorted into four separate rooms adjoining the execution chamber to watch him die.

They will include 10 survivors of the Oklahoma City bombing or family members of victims, 10 members of the media, an unspecified number of government witnesses — and five people chosen by McVeigh.

McVeigh could have designated a sixth witness, a spiritual adviser to watch the lethal chemicals flow into his veins at the federal prison in Terre Haute. But before his original May 16 execution was postponed, he indicated he did not want one.

The four groups will be seated on metal, cloth-covered chairs in separate rooms, each with direct views into the execution chamber. The victims will have tinted glass between them and McVeigh, allowing them to watch him but preventing him from seeing them. For the three other groups, the glass will be clear.

Cate McCauley, a former member of McVeigh's defense team, said she would honor McVeigh's request that she witness his death even though she opposes capital punishment.

"There is a lot of mixed emotions," she said. "Watching a man die certainly is profound. Why he is dying is certainly profound."

McVeigh also chose novelist Gore Vidal, reporter Lou Michel from The Buffalo News — co-author of a book about McVeigh — and defense attorneys Robert Nigh Jr. and Nathan Chambers.

The victims and relatives were chosen by lottery. About 200 others who didn't get picked will watch the execution on closed-circuit TV from Oklahoma City.

Witness Peggy Broxterman plans to arrive Sunday in Indianapolis, where Justice Department officials will pick her up and drive her to Terre Haute. Monday morning, as soon as the execution is over, she plans to head home to Las Vegas.

Her son, Paul Broxterman, 42, was a federal agent killed in the bombing.

"The world seemed brighter," Broxterman said after learning Wednesday that a federal judge had denied a further delay in the execution. "I know it sounds silly. But it was like a big cloud being lifted."

Paul Howell, whose daughter Karan Howell Sheperd, 27, died in the 1995 blast, said his purpose in attending was "to tell people there is someone who is going to watch the execution who is not afraid of McVeigh."

A third group will consist of an unspecified number of federal prison officials and U.S. marshals who will be on hand to witness the first execution of a federal prisoner since 1963.

The fourth group is the media pool. Under federal Bureau of Prisons guidelines, that will include a representative of a daily newspaper in Terre Haute (the Tribune-Star); a daily newspaper from Oklahoma City, (The Daily Oklahoman); and the U.S.-based wire service that serves the most news organizations nationwide (The Associated Press).

The seven other spots will be filled by reporters from three television organizations, two print media organizations, a second wire service and a radio station. Media members seeking to be witnesses will meet at 4 a.m. Monday on the prison grounds to decide among themselves how to allot those spots.
