A former Bangor teacher will serve nine months in jail after pleading guilty Wednesday at the Penobscot County Judicial Center to 13 counts of secretly filming under women’s clothing. Benjamin Emmott, 30, will also register as a sex offender for 10 years. The jail sentence is harsher than the six-month sentence recommended in a plea deal with prosecutors, which Justice Ann Murray rejected based on the magnitude and scope of Emmott’s crimes.
