The local news station has a comments area associated with this story. Several folks posted they were robbed in a similar fashion. They indicated hood rats were targeting the homes because they were upscale for the area. The trash was not locals, but from nearby hoods.
Drugs are always a first thought on home invasions, but this sounds less and less like that is the case.
