ALABAMA OFFICIALS CALLED off the lethal injection of a man convicted of shooting three people because of time concerns and trouble accessing the inmate’s veins.

Alabama Corrections commissioner John Hamm said the state halted the scheduled execution of Alan Miller after they determined they could not get the lethal injection underway before a midnight deadline.

Prison officials made the decision at about 11.30pm last night local-time. 

The last-minute reprieve came nearly three hours after a divided US Supreme Court cleared the way for the execution to begin.

“Due to time constraints resulting from the lateness of the court proceedings, the execution was called off once it was determined the condemned inmate’s veins could not be accessed in accordance with our protocol before the expiration of the death warrant,”  Hamm said.

The execution team began trying to establish intravenous access but he did not know for how long.

Miller was returned to his regular cell at a south Alabama prison.

The 57-year-old was convicted of killing three people in a 1999 workplace rampage, drawing the death sentence.

Justices in a 5-4 decision lifted an injunction — issued by a federal judge and left in place by the 11th US Circuit Court of Appeals — that had blocked Miller’s execution from going forward.

Miller’s lawyers said the state lost the paperwork asking for his execution to be carried out using nitrogen hypoxia, a method legally available to him but never before used in the United States.

When Alabama approved nitrogen hypoxia as an execution method in 2018, state law gave inmates a brief window to designate it as their execution method.

Miller said he turned in paperwork four years ago selecting nitrogen hypoxia as his execution method, putting the documents in a slot in his cell door at the Holman Correctional Facility for a prison worker to collect.

US District Judge R. Austin Huffaker Jnr issued a preliminary injunction on Tuesday blocking the state from killing Miller by any means other than nitrogen hypoxia after finding it was “substantially likely” that Miller “submitted a timely election form even though the State says that it does not have any physical record of a form”.

Prosecutors said Miller, a delivery truck driver, killed co-workers Lee Holdbrooks and Scott Yancy at a business in suburban Birmingham and then drove off to shoot former supervisor Terry Jarvis at a business where Miller had previously worked.

Each man was shot multiple times and Miller was captured after a motorway chase.

Trial evidence indicated Miller believed the men were spreading rumours about him, including that he was gay.

A psychiatrist hired by the defence found Miller suffered from severe mental illness but also said his condition was not bad enough to use as a basis for an insanity defence under state law.

Alabama governor Kay Ivey said in a statement:

In Alabama, we are committed to law and order and upholding justice. Despite the circumstances that led to the cancellation of this execution, nothing will change the fact that a jury heard the evidence of this case and made a decision. It does not change the fact that Mr Miller never disputed his crimes.

“And it does not change the fact that three families still grieve.

“We all know full well that Michael Holdbrooks, Terry Lee Jarvis and Christopher Scott Yancey did not choose to die by bullets to the chest.

“Tonight, my prayers are with the victims’ families and loved ones as they are forced to continue reliving the pain of their loss.”

Although Alabama has authorised nitrogen hypoxia as an execution method, the state has never executed anyone using the method and Alabama’s prison system has not finalised procedures for using it to carry out a death sentence.

Nitrogen hypoxia is a proposed execution method in which death would be caused by forcing the inmate to breathe only nitrogen, thereby depriving them of the oxygen needed to maintain bodily functions.

Many states have struggled to buy execution drugs in recent years after US and European pharmaceutical companies began blocking the use of their products in lethal injections.

That has led some to seek alternate methods.

The aborted execution came after the July execution of Joe Nathan James took more than three hours to get underway after the state had difficulties establishing an intravenous line, leading to accusations that the execution was botched.
