CONCORD, N.H. (AP) — New Hampshire's top court has upheld the sentence of the state's only death row inmate.

The New Hampshire Supreme Court's ruling announced Wednesday opens the way for convicted cop killer Michael Addison to become the first person executed in New Hampshire since 1939.

Addison, who's 33 years old, was convicted of gunning down Michael Briggs in 2006. The 35-year-old Manchester police officer was attempting to arrest Addison on a string of armed robbery charges.

Addison's lawyers argued that holding the trial in a courthouse a stone's throw from the Manchester police department injected passion and prejudice into the jury's verdict.

The ruling comes nearly a year after the court heard unprecedented daylong arguments the first death penalty appeal to come before it in 50 years.
