Derrick Dearman, a convicted axe murderer, is set to be the fourth person Alabama puts to death this year.

On Monday, Gov. Kay Ivey announced Dearman’s execution is set for sometime between 12 a.m. on October 17 and 6 a.m. on October 18. He will be put to death using lethal injection, after he chose the method over nitrogen hypoxia.

Dearman, 35, fired his attorneys earlier this year and told AL.com he wished to stop all appeals of his conviction and death sentence.

“I’ve decided to drop my appeals and have my sentence carried out… I was fairly tried and convicted. I agreed with the court’s decision,” he said in a phone interview from Alabama Death Row this spring.

Dearman was sent to death row—located at William C. Holman Correctional Facility in Atmore—for the brutal slayings of the family members of his then-girlfriend in Citronelle in 2016.

While Dearman said earlier this year that he wasn’t ready to die any time soon, in August he wrote a letter to the Alabama Attorney General’s Office expressing frustration that other men were set for execution before he was.

“I have done everything that is required to drop my appeals and have my sentence carried out and I am compotent (sic) and of a sound mind…can you please respond to this letter to let me know what the hold up is??????”

“All this is hard on not only me but my family and the longer it takes the more me and my family have to go through.”

He’s set to be the fourth person Alabama executes in 2024. First was Kenneth Smith, who was the first inmate killed using nitrogen gas in the country. Smith was executed in January, setting off controversy across the world after Smith writhed on the gurney.

In July, Alabama executed 64-year-old Keith Edmund Gavin for a 1998 murder at a north Alabama ATM. He was put to death by lethal injection, because he didn’t change his method of execution to gas when he had the opportunity to do so in 2018.

The third execution this year is set to happen in September, when Alan Eugene Miller is put to death. Miller, 59, is set to die on Sept. 26 also by nitrogen gas. He’s being executed for the Aug. 5 1999 Shelby County workplace shootings in which he killed Terry Jarvis, 39, Lee Holdbrooks, 32, and Scott Yancy, 28.

In August, Miller’s lawyers reached a confidential settlement with the state and ended his federal lawsuit.

The fifth execution is already set, too. That’s in November, when Carey Dale Grayson is set to be put to death with nitrogen. Grayson was convicted in the 1994 brutal slaying of Vickie Deblieux.
