Proseuction In Tsarnaev Trial Winds Down

The jury at the Boston Marathon bombing trial is seeing autopsy photos of one of the victims. As the prosecution begins to wrap up its case, jurors viewed the autopsy photos of Krystle Campbell. She was one of three people killed by homemade pressure-cooker bombs that exploded at the finish line. Some of the jurors winced and others covered their mouths as they saw the woman's badly burned back and mangled legs that had been riddled with shrapnel. A doctor testified Campbell likely died within a minute of the blasts.

Jurors also examined FBI mockups of the two pressure cooker bombs. Prosecutors say Dzhokhar Tsarnaev and his older brother Tamerlan detonated the bombs with a device built from remote-controlled car parts and a Christmas light. An FBI chemistry specialist testified the bombs contained explosives from fireworks. The government says the two brothers found the instructions for building the bomb in al-Qaeda's "Inspire" magazine. (Metro Networks Inc.)
