The suspect will scout a neighborhood to find a suitable unoccupied home. He will check a city directory publication to determine the name of the homeowner. He will put the name on a phony shipping label and attach that to a box containing rocks or similar type debris. He will then return dressed in an "express delivery" type of uniform. He will pretend to knock or ring the doorbell at the unoccupied house. Getting no answer, he will then go to a next-door or nearby neighbor and ask them to accept the package and pay the C.O.D. fee.
