Shawn Ryan Grell, 30, admitted setting his toddler daughter on fire in 1999, and in 2001, under Arizona law at the time, was sentenced to death by a Superior Court judge. But before Grell had gone through the automatic appeals afforded death-penalty cases, the U.S. Supreme Court made two important decisions regarding the death penalty: that mentally retarded people could not be executed, and that juries, not judges, must decide whether there are aggravating factors that merit the death penalty. Tuesday's decision affirmed a lower court assertion that Grell did not prove he was mentally retarded, but stated that he was still entitled to a jury trial to decide on the death penalty. His murder conviction stands. According to court records, on Dec. 2, 1999, Grell picked up his 2-year-old daughter, Kristen, at her daycare and drove her around until she fell asleep in the car. Then he laid her by the side of a desert road in Mesa, poured gasoline over her and lit it. Grell held a news conference where he confessed to the murder. He chose not to have a jury trial, and in 2000, he was found guilty of first-degree murder. And though the issue of mental retardation was raised as a mitigating factor in his sentencing, the judge ruled that he had not proven it. The Supreme Court justices ruled 4 to 1 to affirm the lower court decision that Grell was not proven to be mentally ill.
