Suzanne Brennan Firstenberg, 61, the artist behind the growing, powerful commemoration she's building outside RFK Stadium, at the edge of D.C.'s Capitol Hill neighbourhood. Washington D.C. native Firstenberg's public art installation called "In America, How could this happen..." is a space reserved for the planting of white flags for every American who has died from the deadly virus. Firstenberg walks among the more than 250,000 flags in the installation.
