I want to know the answer to the following question:
What was Clayton Lockett's cause of death?
All the background I'm provided with is that "The prisoner had to be tasered to restrain him prior to the execution, and the lethal injection missed a vein in his groin, resulting in Lockett regaining consciousness, trying to get up, and to speak, before dying of a heart attack 43 minutes later, after the attempted execution had been called off.". Is that enough to answer the question?
Answer: yes
