Berkeleyside has been following the evolution of the stop sign at the corner of Derby and Warring, where 5-year-old Zachary Michael Cruz was killed Feb. 27, 2009, while crossing the street.

It was a terrible tragedy, one that continues to play out at the stop sign that has become a defacto memorial.

In the year following Cruz’s death, the stop sign was continually decorated with notes and flowers. Then it became moribund.
