MANCHESTER, N.H. (AP) – A man charged with killing a New Hampshire police officer in 2006 has been found guilty of two unrelated charges.

Michael Addison was convicted Wednesday of armed robbery at the El Mexicano Restaurant in Manchester and being a felon in possession of a deadly weapon.

Prosecutors said Addison took part in the robbery one week before Officer Michael Briggs was shot and killed on October 16, 2006. Addison is facing a charge of capital murder in that case.
