A former carrier for a Michigan newspaper has been convicted a second time of murdering his boss.

A jury Tuesday found Nathan Hanna guilty but mentally ill in the 1998 death of Anthony Gillespie, circulation manager at The Evening News in Sault Ste. Marie.

He had pleaded not guilty by reason of insanity. Psychiatrists testified he believed he was killing the Antichrist.

Hanna was found guilty but mentally ill in 1999 and sentenced to life in prison.

But a federal judge ordered a new trial in 2005, saying his conviction was tainted by improper prosecution comments and improper police questioning.

He faces life in prison at sentencing July 8.

Witnesses said Hanna, then 39, walked into the newspaper office carrying a shotgun, spoke briefly with Gillespie, then shot him twice.
