U.S. executions in 2012.

Connecticut abolished the death penalty during 2012 but 11 men remain on death row there.  The Oregon governor placed a moratorium on executions while he remains in office.
All executions are carried out for 1st degree murder and are by lethal injection unless otherwise indicated after the prisoner's name.
