Prisons spokeswoman JoEllen Smith says death row inmate Brett Hartman got to the Southern Ohio Correctional Facility in Lucasville on Monday morning.
The state is preparing to put the 38-year-old Hartman to death by injection Tuesday for stabbing Winda Snipes more than 100 times, then cutting off her hands.
The U.S. Supreme Court is weighing a last-minute appeal by Hartman asking that he be allowed to renew arguments his original attorneys did a bad job presenting evidence that could have led a jury to spare him.
Hartman also argues he is innocent.
Ohio Gov. John Kasich denied Hartman clemency last week.
