Five men who have spent years on death row will soon be executed in Indiana.

On Thursday, Attorney General William P. Barr has directed the Federal Bureau of Prisons to adopt a proposed addendum to the Federal Execution Protocol that allows the United States government to resume capital punishment.

The last federal execution was carried out in 2003.

There is also a new execution protocol that mirrors those used in states like Texas, Georgia and Missouri. This replaces the three-drug cocktail used in past federal executions with a single drug called pentobarbital.

According to a news release from the Department of Justice, 14 states have used pentobarbital in over 200 executions since 2010.

Debra Denise Brown was Indiana's last woman on death row. She will no longer be executed.

“Congress has expressly authorized the death penalty through legislation adopted by the people’s representatives in both houses of Congress and signed by the President,” Barr said in a statement. “Under Administrations of both parties, the Department of Justice has sought the death penalty against the worst criminals, including these five murderers, each of whom was convicted by a jury of his peers after a full and fair proceeding."

Here are the inmates set for execution at U.S. Penitentiary Terre Haute and their crimes, according to the Department of Justice press release:

Daniel Lewis Lee

Lee, a member of a white supremacist group, murdered an Arkansas family of three, including an eight-year-old girl. Lee’s execution is scheduled to occur on Dec. 9, 2019.

Wesley Ira Purkey

Purkey raped, murdered and dismembered a 16-year-old girl in Missouri. He also was convicted in state court for using a claw hammer to kill an 80-year-old woman. Purkey’s execution is scheduled to occur on Dec. 13, 2019.

Alfred Bourgeois

Bourgeois, of Texas, tortured, sexually molested and then beat to death his 2-year-old daughter. Bourgeois’ execution is scheduled to occur on Jan. 13, 2020.

The Department of Justice said additional executions will be scheduled at a later date.
