Boston bombing victim pens poignant open letter to Las Vegas victims: 'You will laugh again

Jeff Bauman, a survivor of 2013's Boston Marathon bombing, wrote a moving status Monday on Facebook, offering victims of the Las Vegas massacre words of strength and encouragement.

Who is Bauman?

Bauman is a double-amputee who survived the Boston Marathon bombing.

After the bombing, Bauman wrote a memoir, 2014's "Stronger," which detailed the bombing as well as his personal struggle to heal.

The book was adapted into a film of the same title, starring Jake Gyllenhaal as Bauman.

"Stronger" was released in September.

What did he say?

Bauman wrote, "To those who lost friends and loved ones — I’m so sorry. I know there are no words that can bring comfort but please know that the world is behind you."

"To the victims waking up in a hospital right now wondering how life will ever be the same ... I know your pain," he wrote. "The most important advice I can give is to remember that healing your mind is just as important as healing your physical, visible injuries. It took me too many years and dark moments to realize that and it is so, so important."

"You will walk again. You will laugh again. You will dance again. You will live again," Bauman promised, before concluding with a link to a GoFundMe page that's raised nearly 9 million dollars in just two days for the Las Vegas Victims Fund.
