Tennessee's head of prisons is resigning following the botched execution of Christa Pike. Tennessee Department of Correction Commissioner Frank Strada is stepping down, a decision he said is "in the best interests" of the state.
Failed execution attempt
Christa Pike survived two lethal injections in a failed execution attempt that left her fighting for her life in hospital. The US convicted murderer was set to be executed on Wednesday evening for the brutal murder of Colleen Slemmer, 19, in 1995.
Historical context
Pike would have become the first woman to be executed in Tennessee in more than 200 years. This is a breaking news story.
