Residents of Boston are marking the first anniversary of the double bombing that struck the city's marathon on April 15, 2013, killing three people and wounding at least 260. Over the past year, photographer Chris Padgett noticed a growing number of Bostonians who commemorated the tragedy with tattoos showing their pride in their city. The trend gained momentum as some tattoo parlors offered to donate the proceeds from Boston-themed tattoos to an aid fund for the bombing victims. Padgett started a photo project called "Bled for Boston" to document, in his words, "the people who dedicated permanent space on their bodies as memorials to their city, first-responders, and the people who lost their lives at the Marathon.”
