Former University of Colorado-Denver graduate student James Holmes is accused in the shooting spree during a midnight showing of the summer's Batman movie.
Veronica's mother, Ashley Moser, was wounded during the shootings. She was left paralyzed and also miscarried.
Holmes was not charged in connection with the miscarriage. Karen Steinhauser, a former prosecutor who is an adjunct professor at the University of Denver, told The Associated Press homicide charges in Colorado only apply to those "who had been born and alive."
