Why was Melissa Lucio’s execution delayed?

HOUSTON (AP) — Nearly half of the jurors who sentenced a Texas woman to die for the 2007 death of one of her 14 children called for her execution to be halted and for her to get a new trial before the state’s top criminal court delayed her lethal injection.
Fifty-two-year-old Melissa Lucio had been set to be executed Wednesday for the death of her 2-year-old daughter Mariah.
The Texas Court of Criminal Appeals on Monday granted her lawyers' request for a stay of execution so a lower court can review new evidence.
The lawyers say the evidence shows Mariah was injured in a fall.
