A mother waiting to die on death row has been given fresh hope of survival just days before her lethal injection - but her supporters fear it will not be enough.
Melissa Lucio, 53, was found guilty of causing the death of her two-year-old daughter Mariah Alvarez, who seemingly died after falling down a rickety old staircase outside their apartment in 2007.
Prosecutors successfully argued that Lucio beat the child to death after her body was found covered in bruises.
