The actual court case itself (from the appeal):
MELISSA ELIZABETH LUCIO v. THE STATE OF TEXAS (concurring)
… there was more than just her confession.
The evidence presented in this case shows that, at about 7:00 p.m. on Saturday, February 17, 2007, paramedics were dispatched to an apartment where appellant lived with nine of her children and an adult male named Robert Alvarez, who was the father of at least seven of these children and whom appellant referred to as her husband. (1) One of the paramedics (Nester) testified that, when the paramedics entered the apartment, they found Mariah unattended and lying on her back in the middle of the floor not breathing and with no pulse. Nester observed that appellant's "distant" and not "overly distressed" behavior was "so far out of the ordinary" that he "put it into the report." Nester also testified that he "noted the fact that [appellant] was not-she wasn't even within arm's reach of the child much less trying to gasp [sic], hold her, or trying to do anything to hold them [sic]."
Appellant told police and paramedics at the scene that Mariah had fallen down some stairs. Mariah was transported to a hospital emergency room where she was pronounced dead. The condition of Mariah's body indicated that she had been severely abused. There were bruises in various stages of healing covering her body, there were bite marks on her back, (2) one of her arms had been broken probably about two to seven weeks before her death, and she was missing portions of her hair where it had been pulled out by the roots. The emergency room physician (Vargas) testified that this was the "absolute worst" case of child abuse that he had seen in his 30 years of practice. Vargas also testified that his emergency-room visual and manual inspection of Mariah indicated no apparent signs of a head injury.
The chief forensic pathologist for Cameron and Hidalgo Counties (Farley), who conducted Mariah's autopsy on Monday, February 19, 2007, testified that Mariah's cause of death was "blunt force head trauma," which would have occurred within 24 hours prior to her death, and it would have been immediately apparent that Mariah was in distress and in need of medical attention. Farley testified that Mariah suffered "multiple contusions" to her head area and that "blunt force head trauma . . . basically means, beat about the head with something-an object, a hand, a fist, or slammed." Farley testified that these injuries would not have been caused by falling down some stairs and that this was the most severe case of child abuse she had ever seen.
