Almost a year after the horrific school shooting at Sandy Hook Elementary, 18-year-old Karl Pierson opened fire at Arapahoe High School in Centennial, Colorado on Dec. 13, leaving one girl critically injured and eventually killing himself. Arapahoe alum AnnaSophia Robb watched the news updates in horror as she saw students of her alma mater scrambling to exit the school and crying in terror.

The 20-year-old CW star, who currently plays Carrie Bradshaw on the "Sex and the City" prequel show, "The Carrie Diaries," took to Twitter to express her dismay at the news.

She begged her fans to pray for the high school as reports started rolling in of the gunman's destruction.

"Please #pray for #ArapahoeHigh- don't know exactly what is going on there with the shooter but Lord keep the kids and faculty safe," she wrote.

"My heart hurts so much right now for my alma mater #ArapahoeHighSchool '#Warriors always take care of each other,'" she wrote.
