LAFAYETTE (CBS SF) — Longtime peace activist Louise Clark, who owned the property on which the “Crosses of Lafayette” war memorial was built, passed away Sunday at age 86.

More than 4,000 crosses have been planted on the hillside adjacent to the Lafayette BART station since Clark and Jeff Heaton, a local building contractor, began the memorial in 2006 to recognize U.S. service members killed in Iraq and Afghanistan, Heaton said.
