BOISE -- The U.S. Supreme Court is refusing to intervene in the case of an Idaho inmate who is scheduled to be executed Friday for killing two women nearly a quarter-century ago.
Paul Ezra Rhoades is scheduled to die by lethal injection on Friday morning. His would be the first execution in Idaho in 17 years.
Rhoades' lawyers asked for time to challenge the state's lethal injection policy. They argued that it amounts to cruel and unusual punishment that is barred by the Constitution.
So far, lower courts have rejected their arguments, and late Thursday, the Supreme Court denied two requests for a stay.
Rhoades was sentenced to death for killing newly married, 21-year-old Stacy Dawn Baldwin and 34-year-old Susan Michelbacher, a special education teacher. He received a term of life in prison for killing 20-year-old Nolan Haddon.
Meanwhile, the Idaho Department of Correction has strict measures in place leading up the execution.
Since the death warrant was issued last month for Paul Rhoades, he was moved from death row to an isolation cell, just down the hall from the execution chamber, where he's been under the watchful eye of guards 24 hours a day.
Here is a timeline of his final hours, according to correction officials:
By 7 p.m. -- Rhoades will be served a last meal of his choice. He will dine at the same time as all other Idaho Maximum Security inmates. The meal he chose will consist of hot dogs, sauerkraut, mustard, ketchup, onions, relish, baked beans, veggie sticks, ranch dressing, fruit with gelatin and strawberry ice cream cups.
By 9 p.m. -- His family members can visit until 8:30 p.m. He will be allowed to make phone calls until 9 p.m. His attorney, Oliver Loewy is excluded, and the warden can approve for others to remain in the cell after that deadline.
At 11 p.m. -- Healthcare services at the prison will offer Rhoades a mild sedative, the sedative is to help Rhoades relax. We are told that he is in fair health in the days leading up to the execution.
Around 11 p.m. -- The prison will go on lock-down. All prisoners will be sequestered to their cells until the execution is completed the next morning.
Around 3 a.m. -- A light snack of saltine crackers and cheese will be offered. IDOC Director Brent Reinke says this is to calm Rhoades stomach before the next round of sedatives are offered.
At 4 a.m. -- Another mild sedative will be offered to Rhoades.
At 7:20 a.m. -- Rhoades will be moved from his isolation cell and taken to the execution chamber.
At 7:45 a.m. -- Witnesses will be escorted into the room where they'll be able to watch the execution.
At 8 a.m. -- The warden will read the death warrant to Rhoades and the witnesses. The warden will then ask Rhoades if he wants to make a final statement.
At 8:07 a.m. -- A final check will be made to make sure there are no legal obstructions.
At 8:10 a.m. -- The lethal drugs will administered.
At 8:30 a.m. -- After 20 minutes passes, a coroner will pronounce Rhoades dead.
Thursday afternoon we got an update on Rhoades's condition. His demeanor is described as anxious and lucid.
Rhoades' attorney, as well as his spiritual advisor can be with him until 6 a.m., as long as Rhoades wishes. The spiritual advisor's identity has not been disclosed. In recent days, Rhoades has been watching TV, reading and doing artwork. He has also been talkative while meeting with family members, his attorney and spiritual advisor.
We are told that other death row inmates at the Idaho Maximum Security Institution signed a card for Rhoades. All but one inmate signed the card.
Three members of the victims' families are planning to attend the execution. Their names have not been released. Rhoades' mother will also be attending.
After the execution, Rhoades' body will be cremated and the remains given to his attorney.
