The release of an Attorney General investigative report that includes references to a Knox County detective who was involved in numerous local drug investigations is being challenged by the officer.

A motion was filed April 28 in Knox County Superior Court by attorney Melissa Reynolds O’Dea on behalf of Lt. Kirk Guerrette. She is asking Justice Jeffrey Hjelm to issue a finding of facts and conclusions of law to support his April 15 order that allows the release of an investigative report to the defendants in the drug cases.

“The defendants have no Constitutional right to engage in a fishing expedition to impeach his credibility,” the motion states.

The motion claims that the judge gave no legal explanation as to why he ordered the release.

The attorney argued that the report should be released only if it could challenge his state of mind during the investigation or to uncover criminal conduct and that neither are the case in this instance.

She said that Guerrette stopped taking the prescription medication — that the defendants might argue affected his state of mind during the drug investigations — in July 2009. Most, if not all, of those drug investigations occurred after July 2009, O’Dea argued in the motion.

She also maintained that Guerrette did not engage in any criminal conduct.

If the judge’s ruling stands, it would affect not only Guerrette but any law enforcement officer who takes prescription medication, she said.

She also argued that any internal affairs investigation documents should not be available if the investigation concluded there was no wrongdoing as was the case in the sheriff’s office review of Guerrette’s conduct.

Guerrette, a 21-year veteran with the sheriff’s office, had been assigned to the Maine Drug Enforcement Agency for the past three years. He was brought back to the sheriff’s department in mid-December. He was promoted by Sheriff Donna Dennison and the county more than a month ago to patrol administrator.

Guerrette is a potential witness in 44 cases since he was a drug officer in those investigations.

Defense attorneys had argued at a March 7 hearing before Hjelm that their clients had the constitutional right to get information that could impeach Guerrette’s possible testimony.

The judge’s order held off the release until May 2 to allow the Maine Health Care Crime Task Force of the Maine Attorney General’s Office time to adjust its wide-ranging statewide investigation.
