As the investigation of the Boston explosions continues, grim details have continued to emerge -- but so have stories of heroism and compassion, from the first responders who ran toward the blasts to help others to the residents who took in stranded marathoners.
We're collecting these stories -- from small acts of kindness to tremendous displays of valor -- and we'll be updating this page as we hear more of them. If you have something to share, we want to hear from you. Send us your stories, photos, videos, and anything else you want to share here. Include a phone number if you'd like to be interviewed. Let us know if you want to remain anonymous.
