Texas is set to execute Robert Roberson Thursday despite all evidence indicating he was wrongfully convicted for his 2-year-old daughter's death.

Last night, Texas death row inmate Robert Roberson narrowly avoided becoming the first person in the country to be executed based on evidence of what was formerly called "shaken baby syndrome," due to an unprecedented intervention by a bipartisan group of Texas lawmakers.
