A Peoria man has been sentenced to 27 years in prison for setting fires at three complexes where he worked.

The trial of 46-year-old James E. Armentrout was set for trial. However, Armentrout pleaded guilty Monday in Peoria County Circuit Court to three counts of aggravated arson in connection with the fires he set on April 18.

Assistant State's Attorney Marcia Straub said Armentrout, who worked as a janitor for a property management company, was arrested in April.

The fire occurred at 4 of the management company's properties in Peoria. Authorities say the fires were set in the maintenance rooms of the complexes. There were no injuries.

Authorities say Armentrout told investigators he had a rash of personal problems and had begun drinking before setting fires.
