New Jersey ? Gov. Jon S. Corzine signed into law Monday a measure that abolishes the death penalty, making New Jersey the first state in more than four decades to reject capital punishment.

The bill, approved last week by the state’s Assembly and Senate, replaces the death sentence with life in prison without parole.

“This is a day of progress for us and for the millions of people across our nation and around the globe who reject the death penalty as a moral or practical response to the grievous, even heinous, crime of murder,” Corzine said.

The measure spares eight men on the state’s death row. On Sunday, Corzine signed orders commuting their sentences to life in prison without parole.

Among the eight spared is Jesse Timmendequas, a sex offender who murdered 7-year-old Megan Kanka in 1994. The case inspired Megan’s Law, which requires law enforcement agencies to notify the public about convicted sex offenders living in their communities.
