The mother of one of the 26 victims of 2012's Sandy Hook Elementary School massacre has written a powerful letter to the teachers of America.
Nebla Marquez-Greene had two children attending Sandy Hook Elementary that day. Her daughter, 6-year-old Ana Grace, was killed in the Connecticut massacre, and her son was uninjured in the attack.
Her letter, which was posted on the Education Week website is powerful, gut-wrenching and encouraging all at once. Read it after the jump.
