Prosecutors believe Boston Marathon bombing suspects Dzhokhar and Tamerlan Tsarnaev built bombs using Christmas lights and radio car parts in the explosive devices planted along Boylston Street. The revelation was made in documents filed with the court on Wednesday, according to The Boston Globe.
From the Globe:
"The Marathon bombs were constructed using improvised fuses made from Christmas lights and improvised, remote-control detonators fashioned from model car parts," prosecutors wrote. "These relatively sophisticated devices would have been difficult for the Tsarnaevs to fabricate successfully without training or assistance from others."
Also, prosecutors said, Tsarnaev and his older brother, Tamerlan, appear to have crushed and emptied fireworks containing black powder to make explosive fuel for the bombs.
