Five years after Sandy Hook

"Many relatives of the 26 children and educators killed five years ago [today] at Sandy Hook Elementary School [in Newtown, Conn.] have dedicated themselves to charity, activism and other efforts to channel their grief and, in many cases, to help prevent violence," AP's Pat Eaton-Robb writes.

More of their projects:

• "Others have jumped into the policy fray to lobby for gun control or improved mental health care. In some cases, they have traveled the country, and even the world, as recognized experts in their fields, such as Jeremy Richman, a scientist whose Avielle Foundation for the study of brain health is named for his slain daughter.
• "The Sandy Hook families have created a website to share each of their stories and information about the various projects they have started in memory of their family members."
