The Tsarnaev brothers reportedly learned how to build a pressure-cooker bomb from a jihadi magazine, but apparently that guide didn't include a step instructing them to throw out evidence of their purchases. On Wednesday, the jury deciding accused Boston bomber Dzhokhar Tsarnaev's fate were shown pictures of inside his family's Honda Civic as well as his older brother Tamerlan's wallet, which contained receipts for bomb-making ingredients. Tamerlan was killed in a dramatic shootout with police, but his brother escaped for several hours before being caught hiding in a dry-docked boat. Tsarnaev, 21, faces the possibility of the death penalty for his role in the 2013 deadly bombings. Three people were killed and more than 260 were injured when two pressure-cooker bombs exploded near the finish line of the marathon.Jury was shown pictures of Tamerlan Tsarnaev's wallet on WednesdayExperts testified that his fingerprints were on receipts for a gun and ammo store and Target where he purchased two backpacksThe alleged Boston bomber was killed in a shootout with police, but his younger brother Dzhokhar escaped and is currently on trialGloves with blood matching slain MIT officer Sean Collier were found on drivers-side of Tsarnaevs' Honda CivicHowever, none of Collier's blood was found on Dzhokhar's sweatshirt
