When Summer Phelps was brought to the emergency room on March 10, 2007, the treating physician thought the 4-year-old was a cancer patient because of her injuries, according to testimony Monday in the homicide-by-abuse trial of her father, Jonathan Lytle. Dr. Darrol C. Hval, an emergency room physician at Deaconess Medical Center, said the 45-pound child was covered from head to toe with purple bruises and large chunks of her long red hair were missing.
