Who were the three idiots?

The New York Times has the whole story by Robbie Brown:

A state jury announced Thursday that it could not reach a unanimous decision on whether Brian G. Nichols deserves the death penalty for committing a spree of murders, assaults and hijackings in 2005 that terrified Atlanta. The jurors, deadlocked after 20 hours of deliberation, told Superior Court Judge James G. Bodiford that they were split 9-3, but did not say if the majority favored death or life in prison. The defense called for a mistrial, but the judge ordered jurors to continue deliberating until 1:30 p.m. while he met with the lawyers.
The jury convicted Mr. Nichols on 7 November of murdering four people, stealing five cars, kidnapping a woman, and evading police in a chase across Atlanta. He was on trial for rape on 11 March 2005, when he stole the gun of a sheriff’s deputy, shot a judge, a court reporter, and a deputy at the Fulton County Courthouse, then killed a customs official during his escape. The spree, known here as the Courthouse Shootings, has transfixed Atlanta for three years and cost the county more than $3 million in legal fees.
Jurors have three sentencing options: the death penalty, life in prison with parole, or life without parole. Under state law, their decision must be unanimous in order for Mr. Nichols to receive the death penalty. If the jury remains hung, the judge will determine the sentence, although he may not select the death penalty.

Rico says he hopes they can live with themselves, but this seemed like such a straightforward case for the death penalty...
