Grace McDonnell was one of the 20 children killed at Sandy Hook Elementary School this month. As her parents are grieving the loss of their bright-eyed, seven-year-old daughter, they can take at least some solace in a sign of comfort that she left behind.

Grace was known for leaving messages on the family’s bathroom window — notes and symbols that would show up once fog clouded the room from shower steam. And the day after her death, seemingly on cue, one of these notes appeared to her mother.

On the first day without her daughter, Lynn McDonnell said that the message on the window was a peace sign, Grace’s favorite symbol. Above it were the words, “Grace, Mom.” CNN was moved to call the family’s finding “a message from beyond the grave.”

“I looked and there was her peace sign in the window and I was like, ‘That’s a sign from my Grace,’” Lynn said. ”She was all about peace and gentleness and kindness.”

Lynn described her daughter as immensely happy, claiming, “She was just the light and love of our family.”
