A former Menominee County Sheriff’s Deputy who was convicted of sexual misconduct involving a teenage boy last year was arraigned in the Menominee  District Court on Friday on a new 11-count felony complaint of sexual assault. 57 year old Brian Helfert of Menominee had been sentenced in December to six months in jail. The new charges arise from a number of incidents alleged to have occurred with another victim between April 2013 and December 2019. The facts filed with the Court in support of the felony complaint allege a six-year history of sexual assault and abuse of the victim at the hands of Helfert. The victim reported to police that he felt compelled to come forward at this time when he learned of Helfert’s plea and sentencing in the other case. An investigation by the Menominee Police Department  led to the arrest of Helfert.

Menominee County Prosecuting Attorney Jeffrey T. Rogg said he will be personally handling the case and is not seeking the appointment of a special prosecutor.

A Preliminary Examination is scheduled for May 21 at 8:30 a.m. Judge Robert Jamo set bond in the amount of $250,000.00, cash or surety.

Rogg invited other potential victims to come forward, saying that “every allegation against Mr. Helfert will be fully investigated by the MPD and can still be prosecuted by me.”
