Three inmates across the country are set to be executed on Thursday.

According to the Death Penalty Information Center, Thomas Whitaker is set to be executed in Texas, Eric Branch in Florida, and Doyle Lee Hamm in Alabama.

If the three executions are carried out, it will be the first time in eight years that three executions happened on the same day, the non-profit organization reported.

According to Reuters, 38-year-old Whitaker is set to die for masterminding a 2003 plot that left his mother Tricia and teenage brother Kevin dead. His father was also shot, but survived his injuries and has asked the state for clemency for his son. Yesterday, the Texas paroles board also recommended clemency in a unanimous decision. The governor has not responded to those requests.

Branch, 47, is planned to be executed for a 1993 killing of a college student. Reuters reported the jury in Branch's case did not unanimously recommend the death penalty, and the state has blocked similar cases from executions in the past.

Hamm, 61, is set to die Thursday at 6 p.m. at Homan Prison. He was convicted in the 1987 murder of Cullman motel clerk Patrick Cunningham. A federal judge denied his lawyer's request for an emergency stay of execution yesterday, but Hamm's legal team is currently arguing the case in the 11th Circuit Court of Appeals.
