An 8-year-old called 911 when her father was having a medical emergency, and her mother was not home. Adriana Wailes explained to a 911 operator that her father "has brain cancer and he just started shaking." When first responders got to the house outside Denver, Adriana led them inside where her father, John, was. He was conscious as they rushed him to the hospital. John tells Inside Edition that Father's Day would have been very different if Adriana had not known to call 911. #dad #girldad #pa
