Dzhokhar Tsarnaev was indicted on the charges after he and his older brother Tamerlan planted the devices near the finish line at the famous race two years ago (15Apr13).

Three people were killed and more than 260 injured as two explosions rippled through the crowds, where people had gathered to watch runners cross the finish line, while a police officer was fatally shot three days later, during a confrontation with the brothers.

Tamerlan Tsarnaev, 26, died in a subsequent shoot-out with cops at the end of a massive manhunt.

Dzhokhar, 21, went on trial for the charges last month (Mar15) and on Wednesday (08Apr15), after just over a day of deliberations, the 12 jury members returned guilty verdicts on all counts, including bombing a place of public use, malicious destruction of property resulting in death, conspiracy to use a weapon of mass destruction and using a weapon of mass destruction.

A number of the charges carry the death penalty.

Sentencing is expected to start next week (begs13Apr15).
