A bathtub and kitchen sink in the Cambridge, Mass., apartment of deceased Boston Marathon bombing suspect Tamerlan Tsarnaev tested positive for residue from explosives, corroborating his surviving brother's claims the duo built bombs at the home, a federal law enforcement source said Friday.
The testing was performed by federal explosives experts, and the results suggest bombs were either built in the bathroom and kitchen or stored there at some point, the source said.
Information about the residue came to light as federal, state and local authorities launched a massive search effort in a wooded area and other locations near the University of Massachusetts Dartmouth campus for evidence related to the Boston Marathon bombings case, according to the source.
Federal agents have received information that students heard explosions in the wooded area about a month ago, sparking concerns among investigators the area may have been used as a testing grounds for the pressure-cooker bombs that killed three people and injured more than 260 at the Boston Marathon on April 15.
