Dozens of volunteers gathered at Chestnut Hill Presbyterian Church, 8855 Germantown Ave., to create a memorial for 331 people killed by guns in Philadelphia in 2012.

The memorial was the work of Heeding God’s Call, a Northwest Philadelphia faith-based organization dedicated to reducing gun violence through a number of actions, including regular protests at area gun shops.

Reverend W. Jarrett Kerbel of St. Martin-in-the-field, who organized the work today, said the project was the idea of church youth groups — many of the youth group members from both churches were working to build the memorial. Heeding God’s Call sponsored the work.

The video includes remarks from Heeding God’s Call executive director, Bryan Miller, Reverend Cindy Jarvis of Chestnut Hill Presbyterian and Kerbel.
