The Execution Did Not Go Well

From April 30, 2014 USA Today:

Clayton Lockett, 38, struggled violently, groaned and writhed after lethal drugs were administered by Oklahoma officials Tuesday night, according to eyewitness accounts. State Corrections Director Robert Patton halted the Lockett's execution, citing vein failure that may have prevented the deadly chemicals from reaching Lockett. He eventually died of a heart attack.

Witnesses could see Lockett struggle before state officials closed off curtains blocking their view.

Unnecessary suffering should be avoided, I agree.  But it sounds like he got off light compared to his victim:

Lockett, who was convicted of shooting 19-year-old Stephanie Neiman and watching two accomplices bury her alive in 1999,... 

Another person that was scheduled for execution is this charming number:

Warner's execution had been set for 8 p.m. Tuesday. The 46-year-old was convicted of raping and killing his roommate's 11-month-old daughter in 1997. He has maintained his innocence.

Well, of course.  Who would confess to a crime that horrible?
