The boy killed in the San Bernardino school shooting had a rare disorder that causes challenges — and inspires creativity

It's so sad this little boy got caught up in somebody else's madness.

Washington Post reports at only 8 years old, Jonathan Martinez was already a survivor.

He had endured heart surgery and many other challenges presented by Williams syndrome, a rare neurodevelopmental disorder marked by cardiovascular disease, developmental delays and learning disabilities, as well as impressive creative talents.

Jonathan was fatally struck as he stood near his teacher, Karen Elaine Smith, who was shot dead by Cedric Anderson, her estranged husband.
