PHOENIX — The Arizona Supreme Court has concluded that a man was mentally
disabled and cannot be executed for murdering his 2-year-old daughter by dousing
her with gasoline and setting her on fire.
The state Supreme Court’s unanimous ruling Wednesday overturns Shawn Ryan
Grell’s death sentence, reducing it to natural life in prison.
Grell was convicted of the Dec. 2, 1999 murder of Kristen Grell in the
desert near Mesa.
The court’s ruling said the killing was “horrific” and devastating to the
family but that Grell’s sentence must be reduced.
The justices said that’s because the U.S. Supreme Court has ruled that it would
be constitutionally prohibited cruel and unusual punishment to execute someone
with mental retardation.
One of the previous Supreme Court opinions in Grell’s case responded to his claim
that he had mental retardation. The second sent his case back to Superior Court
so he could be sentenced by a jury instead of a judge.
