The police helicopter tracked the driver to the intersection of Buchanan Avenue and Plaster Creek Boulevard, where the motorcyclist took to a sidewalk, then turned onto a dirt path in some woods.

After this, it received the earth plaster made of dirt, sand and natural fibers, which was mixed by bare feet and manually applied to the wall.
