The person or persons who did this are sick in the head. Hopefully they're caught soon, and punished accordingly. Death penalty if I had my way.
The explosives that killed three people and injured more than 170 during the Boston Marathon on Monday were most likely rudimentary devices made from ordinary kitchen pressure cookers, except they were rigged to shoot sharp bits of shrapnel into anyone within reach of their blast and maim them severely, law enforcement officials said Tuesday.
The pressure cookers were filled with nails, ball bearings and black powder, and the devices were triggered by ?kitchen-type? egg timers, one official said.
The resulting explosions sent metal tearing through skin and muscle, destroying the lower limbs of some victims who had only shreds of tissue holding parts of their legs together when they arrived at the emergency room of Massachusetts General Hospital, doctors there said.
Law enforcement officials said the devices were probably hidden inside dark nylon duffel bags or backpacks and left on the street or sidewalk near the finish line. Forensic experts said that the design and components of the homemade devices were generic but that the marking ?6L,? indicating a six-liter container, could help identify a brand and manufacturer and possibly lead to information on the buyer.

At this stage of an inquiry, officials said it was not unusual for there to be no suspects. But with the paucity of leads, Mr. DesLauriers and others pleaded with members of the public to submit any photographs or video they may have taken at the blast site to help in the investigation. At the briefing, Mr. DesLauriers said that someone somewhere almost certainly heard a mention of the marathon or the date of April 15.
?Someone knows who did this,? he said. ?Cooperation from the community will play a crucial role.?

Counterterrorism specialists said the authorities would aim to match the faces of any possible suspects, using facial recognition software, against an array of databases for visas, passports and drivers? licenses. ?It?s our intention to go through every frame of every video that we have to determine exactly who was in the area,? Edward Davis, the Boston police commissioner, said at the news briefing. ?This was probably one of the most well-photographed areas in the country yesterday.?
