Hoffman is charged with the following:

  • Second-degree sexual assault
  • Dangerous weapons on school premises
  • Strangulation and suffocation

According to the criminal complaint, Hoffman and a 17-year-old girl went for a drive on December 7th -- and ended up at Mary Knoll Park. At that point, the complaint indicates Hoffman began to be physical with the girl and demanded she take off her clothes.

The alleged victim in this case told police "she was reluctant to take off her clothes," however, she knew Hoffman had a knife on him at all times. She previously "told him this scared her and she did not like it."

The complaint says Hoffman then had inappropriate sexual contact with the girl. At one point, the girl told investigators she "felt like she was going to die" because Hoffman grabbed her neck so she couldn't breathe.

"It's an extremely traumatic occurrence," Angela Mancuso said.

Mancuso helps victims who have lived through similar experiences.

"The Women`s Center works with adult and child survivors of domestic violence, sexual assault and abuse. We do that through short-term crisis counseling. We have a 24-hour hotline emergency crisis shelter," Mancuso said.

Mancuso said she encourages victims in situations like this to seek help and counseling.

"There are resources available for survivors of sexual assault and we want them to know they are not alone -- that we will stand by them and support them," Mancuso said.

On January 4th, a detective investigating this case was at Brookfield Central High School when Hoffman was brought into the office. Hoffman was searched -- and investigators took custody of Hoffman's backpack. Inside, the detective "located a Tac-Force Speedster model brown-handled knife." The complaint indicates the knife is designed to be opened with one hand. The associate principal at the school also turned over a black Huskie folding knife which had been located "during a search of the defendant's vehicle parked on the property of Brookfield Central High School."

Hoffman made his initial appearance in court in this case on January 6th.

He'll next be in court on February 3rd for his preliminary hearing.

Officials with the Elmbrook School District said Hoffman is no longer enrolled at Brookfield Central High School.

If convicted on the assault charge, Hoffman faces up to 40 years in prison and $100,000 in fines. The strangulation charge comes with a maximum six years in prison and $10,000 in fines.

The dangerous weapons on school premises charge has a maximum penalty of nine months in prison and $10,000 in fines.

    I can’t imagine how difficult it was for the victim to come forward. Only 17-years-old and she had the courage to tell her story to police. Pretty amazing.

  • Condemned before found guilty

    It seems that these comments all are condemning this boy just because he has been charged. He has not been convicted or been able to tell his side publicly. How do we know this wasn’t a girlfriend (relationship recently ended) who was angry and wanted to hurt him? (Young women claim false rape too…Rolling Stone false rape report comes to mind) For the record, I am a mother of two teen daughters and I pray daily that they don’t get caught in a situation. I encourage group dating.

    All I am saying is there are two sides to every story. Both involved here are 17 years old and 17 yr olds are very irresponsible & don’t always think through their actions/words. If she is telling the truth, I pray for her healing. If she is lying, I pray the truth comes out so this boy doesn’t have his whole life ruined.
    As for weapons on school grounds, I’m not okay with that. My daughter says many guys have knives at school. That is worrisome and somehow needs to be addressed.
