In 1978, Warren McCleskey, a black man, was convicted in the Superior Court of Fulton County, Georgia, of two counts of armed robbery and one count of murder arising from the robbery of a furniture store in which a white police officer was killed.
McCleskey and three accomplices, all armed, planned and carried out the robbery. McCleskey secured the front of the store, forcing customers to lie down, while the others tied up employees and took receipts, a watch, and six dollars. When a police officer responding to a silent alarm entered, two shots were fired, both striking him, one fatally in the face.
At trial, the State introduced evidence that at least one of the bullets that struck the officer was fired from a .38 caliber Rossi revolver matching the gun McCleskey had carried. The State also introduced the testimony of two witnesses who had heard McCleskey admit to the shooting. The jury convicted McCleskey of murder.
At the penalty hearing, the jury found two statutory aggravating circumstances beyond a reasonable doubt: the murder was committed during armed robbery and upon a peace officer engaged in the performance of his duties. McCleskey offered no mitigating evidence. The jury recommended death on the murder charge and consecutive life sentences on the robberies. The court imposed the death sentence.
The Georgia Supreme Court affirmed the convictions and sentences in 1980. This Court denied certiorari. After state habeas relief was denied, McCleskey filed a federal habeas petition in the Northern District of Georgia raising 18 claims, one of which was that the Georgia capital sentencing process is administered in a racially discriminatory manner in violation of the Eighth and Fourteenth Amendments.
He supported this with the Baldus study, a statistical analysis of over 2,000 murder cases from the 1970s examining more than 200 variables. The raw numbers showed defendants charged with killing white victims received the death penalty in 11% of cases, compared to 1% for killing black victims. When divided by race combinations, black defendants killing white victims received death in 22% of cases, white defendants killing white victims in 8%, black defendants killing black victims in 1%, and white defendants killing black victims in 3%.
After controlling for 230 nonracial variables, one model showed defendants killing white victims were 4.3 times as likely to receive death, and black defendants 1.1 times as likely. The District Court held an evidentiary hearing and found the study statistically valid but flawed in methodology and insufficient to show racial considerations in McCleskey's case or a prima facie case. The Eleventh Circuit, en banc, assumed the study's validity but held the statistics insufficient to demonstrate discriminatory intent or unconstitutional arbitrariness. The Supreme Court granted certiorari in 1986, limited to the equal protection claim.
