Republicans express alarm that Texas execution nearly went ahead

Lawmakers unhappy with handling of Robert Roberson case as doubts grow over science used to secure conviction

Republican lawmakers in Texas expressed alarm on Monday at the apparent willingness of state officials to execute a potentially innocent man on the basis of junk science, as the political fallout of the 11th-hour reprieve of Robert Roberson continued to roil the state.

Several Republican members of the state's House committee on criminal jurisprudence lined up to air their discontent with the handling of the case of Roberson, 57, who was convicted of killing his two-year-old daughter Nikki Curtis in 2002 by violently shaking her.
