At the point that Connecticut abolished the death penalty in 2012, 11 people in that state were on death row. Those prisoners now won't be executed because of an August, 2015 ruling by the Connecticut Supreme Court. In a decision that invoked the concept of cruel and unusual punishment, the court declared the state's capital punishment system unconstitutional.
The decision doesn't alter the numbers of states considered to employ the death penalty. You can see the Death Penalty Information Center's report on the jurisdictions that have and don't have capital punishment.
