A pair of sisters, aged 7 and 9 years old, want answers as to why San Diego Police and members of their church refused to prevent the death of their oldest sister, Arabella McCormack. Arabella McCormack, just 11 years old at the time of her death on August 30 of last year, died from severe malnutrition and abuse at the hands of their adoptive parents, Brian and Leticia McCormack. McCormack was reportedly just 40 pounds when Sheriff's deputies arrived at the family's Spring Valley home on a report of a child in distress. McCormack died shortly after from heart failure. The girls' adopted father, Brian McCormack, a Border Patrol Agent, shot himself to death inside his truck hours after deputies were called to the home. The girls' mother, Leticia McCormack, and her father have since been charged with murder in Arabella's death.
