Christa Pike's lawyers seek to preserve evidence from botched execution

The lawyers of US death row inmate Christa Pike have asked for evidence to be preserved from her botched execution. 

The 50-year-old survived two lethal injections in Tennessee last week – a death sentence imposed for murder in 1996. 

A statement from her lawyers yesterday stated she's now conscious and speaking, still handcuffed in hospital, and receiving critical care. 

US Correspondent Nick Harper told Andrew Dickens Pike's lawyers argue there were problems with the IV lines involved. 

They claim at least seven needles were used to try to get the doses into her system, one even bent at a 90-degree angle.
