OWOSSO, Mich. -- Newly released documents said a trucker took two nieces and a teen boy to school before fatally shooting an abortion protester and another man in a small Michigan town.

The documents said Harlan Drake confessed to killing James Pouillon and Mike Fuoss.

His statements to Owosso police are in an affidavit that was used to justify a search of his apartment and truck after the Sept. 11 shootings. The affidavit was available Friday after being sealed for 56 days.

Drake is charged with first-degree murder and gun violations. His lawyer is considering an insanity defense.

Drake told police that he drove two nieces to school in Corunna and then dropped off a niece's boyfriend at Owosso High School.

Pouillon was shot near the school while protesting abortion.
