The state of Texas is set to execute one of the longest-serving inmates on the state's death row after he has spent three decades trying to halt the punishment, according to Reuters.

Lawyers for Bower filed a last-minute appeal with the US Supreme Court last week seeking to prevent the execution by lethal injection scheduled for 6pm local time today at the state's death chamber in Huntsville.
The state said he is guilty of fatally shooting the four men in a deal for a $4,000 ultra-light airplane that went bad and there is no compelling legal reason to further delay the execution.
Bower has faced imminent execution six times while in prison.
