Remembering the Aurora Massacre

Seven years ago today this little girl went to the movies and never came home.
Her name is Veronica Moser Sullivan.
She was six year old and was shot four times.
Her mother Ashley suffered critical injuries and was rendered a paraplegic. One week after the attack she miscarried.
Twelve people were killed and 70 others were injured that night at the Century movie theater in Aurora, Colorado. How many more have to die?
