Investigators Checking Crapo Hill Landfill

FBI and State Police have been combing through mounds of trash at New Bedford's Crapo Hill Landfill in search of items dumped there from a New Bedford apartment dumpster. A source says investigators are looking for a black trash bag with a backpack inside believed to belong to marathon bomb suspect Dzohkar Tsarnaev. Since Monday, officials have brought in dogs and a hazmat crew to help in the search. The trash comes from the apartment complex where 3 people were arrested Friday, believed to have ties with

Tsarnaev. The area has been taped off with crime scene tape and guarded by a police officer.
