US murderer whose execution failed in Tennessee is conscious and talking

Krists Paiks (the name as rendered in the Latvian-language source), an American murderer whose execution in the US state of Tennessee failed a week ago, is now conscious and talking. The BBC reports this.

The man is 50 years old. The execution did not go as planned because he stayed alive even after two injections had been administered. Those injections were meant to be lethal.

The source text gives no other information. It does not say why the procedure failed. It also does not describe the man's health or say whether another attempt to carry out the sentence will be made.
