(Portland, OR) -- Portland Police searched the apartment of a prolific graffiti vandal who identifies himself as MONK6. His tags are in highly visible locations and require technical climbing skills. They're also difficult to remove. Dozens of cans of spray paint and thousands of drawings were recovered. Special prosecutors are handling the investigation. Police also released information about a female tagger known as BAMBI. Darvin Duffield pleaded guilty and was ordered to pay over 10-thousand dollars restitution.
