NEW YORK (CBSNewYork) — CBS 2 has learned new details about the type of bombs used in the deadly Boston Marathon blasts. They had nails inside and that’s not all.
Investigative reporter Tamara Leitner has learned that police believe at least one of the bombs was placed in a metal pressure cooker with a locking lid.
There are several reasons why this may have been used. It’s a common kitchen item and doesn’t appear suspicious. Pressure cooker bombs are also fairly simple to make. And when the bomb explodes, the metal pot becomes shrapnel.
