Andrew Allen Ziegenfelder, 30, pleaded guilty to conspiracy to commit extraction of marijuana concentrate, a Class 3 drug felony, during an arraignment hearing at the Boulder County Justice Center.

Prosecutors dismissed the other original charges of extraction of marijuana concentrate, processing or manufacturing marijuana or marijuana concentrate, possession with intent to manufacture or distribute marijuana or marijuana concentrate, and fourth-degree arson as part of the plea deal, court records show.

Ziegenfelder’s co-defendant, Paul Garrett, was sentenced in June to two years of probation and 100 hours of community service.

According to an arrest warrant affidavit, the investigation into the house at 1035 Baker St. in Longmont began after neighbors reported a fire the evening of Oct. 8.
