There have been several new developments today in the Boston bombings case.
Authorities are searching a landfill for a laptop believed to be tied to the Boston Marathon bombers,
according to CNN.
Information from Dzhokhar Tsarnaev himself, plus other leads, spurred authorities to look through the New Bedford, Massachusetts, landfill, the official told CNN's Susan Candiotti. The 19-year-old went to school -- at the University of Massachusetts-Dartmouth -- in an adjacent town, and he was spotted in his dorm room there in the days after the April 15 twin blasts that left three dead.
ABC News also has more on this development.
The lead regarding the laptop resulted from interviews authorities conducted with acquaintances of the suspects.
From the same ABC News report, we learn that the two acquaintances, who are from Kazakhstan, have been arrested by immigration officers on a violation of their student visas.
