DALLAS (AP) A Texas death row inmate who was scheduled to die next week had his execution stayed Friday by the state's highest criminal court, which wants to review a petition that argues he is not mentally competent to be executed.

Marcus Druery, 32, was condemned for the 2002 shooting and robbery of 20-year-old Skyyler Browne at Druery's family property in rural Brazos County. His execution was scheduled for Wednesday.

The Texas Court of Criminal Appeals ordered its stay after a lower court rejected Druery's petition. An attorney for Druery, Kate Black, said he was diagnosed with schizophrenia and was deemed incompetent by a defense expert. She says executing Druery would violate the U.S. Constitution's ban on cruel and unusual punishment.

The U.S. Supreme Court has ruled that prisoners can't be executed unless they're aware of the punishment and know why they're being punished.

"We are hopeful the Court will find that Mr. Druery is entitled to a full and fair hearing to present the evidence of his severe psychosis and establish his incompetence to be executed," Black said in an emailed statement.

Brazos County District Attorney Bill Turner said prosecutors do not dispute that Druery has a mental disorder, but they believe he's competent enough to face execution.

"We anticipated the appellate courts would take a look at it before the execution proceeded," Turner said in an interview Friday.

Druery was the next death row inmate scheduled to be executed. Two other inmates have scheduled executions in August.

Texas, the nation's most active death penalty state, has executed six prisoners this year and 483 since 1982.
