Three-year-old Knijah Bibb was visiting a relative when a bullet fired outside came through the house and killed her.Tyler Johnson lost his life at age 25, one of the victims of a random shooting at a shopping mall.Ruthanne Lodato was fatally shot by a stranger who had knocked on the door of her home.The music teacher was 59.They were among 155 gunshot victims commemorated at the Memorial to the Lost on a recent Sunday.Each T-shirt displayed on the lawn bears the name, age and date of death of one of the people killed by guns in the Washington area last year.The victims'ages ranged from 3 to 73.While the display isn't going to fix anything, it does heighten the awareness.It gives us opportunities to start talking about it from a position of peace building rather than out of reaction and defense.A faith-based organization, Heeding God's Call, began the Memorial to the Lost, also known as the T-shirt Memorial, in Philadelphia in 2013.It was to commemorate the 288 people who were gunned down in the previous year in the area.Since then, in collaboration with churches, synagogues and mosques, the group has sponsored installations in over 50 sites in other cities.
