Boston bomber Dzhokhar Tsarnaev has been sentenced to the death penalty for 30 criminal counts including the injury of hundreds and death of three people, as well as the murder of an MIT police officer.

Tsarnaev was convicted at 3:30 PM on Friday, May 15. The jury took 18 hours to reach a decision, choosing to ignore the defense’s argument that he was manipulated by his fanatical older brother, Tamerlan Tsarnaev, into the violent attack.

Most death penalty cases can take years to reach an end, meaning Tsarnaev, age 21, will spend an indeterminate amount of time on death row before execution or appeals.
