A Texas teen girl accused of torturing her eight-year-old brother to death alongside her boyfriend insisted she is innocent and would never harm the little boy.
Kara Walker, 17, and her boyfriend Nolan Stallings, 18, were arrested in connection to Charles Walker's death and charged with felony injury to a child.
Charles died on February 10, days after he was taken to hospital in critical condition - with injuries that were consistent with abuse, including a crack skull, according to police.
Prosecutors said the couple tortured the boy 'over several days' at Stallings' home in Highlands, near Houston, before his death.
They also said they were not ready to say why the 'most serious' charges had not been filed against the teen couple.
