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. According to Druery's attorney, he was diagnosed with schizophrenia and was deemed incompetent by a defense expert. Therefore, executing Druery would violate the U.S. Constitution's ban on cruel and unusual punishment. 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.
