Streets of the Dead- Washington Post -March 16.
When Washington youths get killed, memorials pay testament to the victims -

"They are street memorials that spring up to mark the places where mostly young people get killed. Photographer Lloyd Wolf began documenting them in 2003 after a boy he mentored lost four relatives to murder in a year. He watched the boy stagger in his pain.
'I learned to see the markers that were erected in the city's rough (and not-so-rough) neighborhoods as representing the powerful emotions of people -- real people, distraught and grieving.'" Wolf says about his photos.

"The memorials take on different forms in different parts of the country, Wolf says. In New York City, mourners pay tribute with elaborate graffiti on streets and walls. They are freestanding in the Southwestern cities of Albuquerque and Austin, like those that dot the sides of the road. They draw influence from Catholic and Latin American images and symbols: crosses, photos in gilded frames and pictures of saints on candles in glass holders.
Here, they might feature handwritten notes and photos. There are flowers and, most especially, toys, their cheeriness repurposed to aching effect: lions and tigers, rabbits and bears. The memorials spring from a collective will that could not save the dead and now offers eulogy and demands justice in tufts of fake fur"

There are nine photographs in a slideshow on the newspaper's site, and on his own blog Wolf has posted hundreds.
Washington's Other Monuments
"These pictures are of the many sad memorials erected by friends & family to honor murder and other violence victims in the Washington DC area. These spontaneous, homemade, heartfelt creations are found on streets throughout the region. They are often the only physical tribute to the many slaying victims.
