After a dramatic shootout with police in New Jersey today, a 28-year old man is in custody, charged with the bombings in New York and New Jersey over the weekend.
Ahmad Khan Rahimi is described as a naturalized citizen of Afghan descent who had been living with his family and helping run their fast food restaurant in New Jersey.
On Saturday morning, a pipe bomb exploded near the course of a charity race in New Jersey. No one was hurt in the blast, but later that day, 29 people were injured in the Chelsea neighborhood of Manhattan when a pressure cooker bomb exploded. A second bomb found in the area failed to detonate.
We're still learning more specifics about the explosives used, but pressure cookers in particular have been configured into improvised explosive devices for years, including in the 2013 Boston Marathon bombing.
