A Rock County judge sentenced 24-year-old Ethan Brown of Rockford, Illinois, to 33 years in the Wisconsin prison system on August 7, split between 20 years of initial confinement and 13 years of extended supervision. The sentence closes out a case rooted in 2017 and 2018, when Brown, then 17, traveled from Illinois to Beloit for gatherings of friends and extended family and molested a seven-year-old girl in a basement during those visits.
Circuit Court Judge Derrick Grubb handed down the sentence after a jury convicted Brown on May 6 of child enticement and two counts of first-degree child sexual assault, following a three-day trial in Rock County Circuit Court, according to WCLO. As reported by WMTV 15 News, police say Brown took two other children into the basement to play before touching or fondling them, and those children later made statements alleging similar abuse.
Brown had faced up to 95 years in prison across the three felony counts, according to Big Radio, before Judge Grubb imposed the 33-year term. At the hearing, Grubb told Brown that he was a sex offender who showed no remorse, per the same account from WMTV 15 News.
A Delayed Disclosure Breaks the Case Open
The case sat dormant for years before the victim told her mother what had happened in 2025, prompting Beloit Police Department detectives to open an investigation. Detectives then interviewed two additional child victims who provided corroborating statements, according to Big Radio. Beloit Police child maltreatment officer Dylann Rauch led the investigation, with detective Eric Shoonover also participating, per WMTV 15 News.
At sentencing, the victim spoke directly to the court about why she chose to come forward. “Sharing my story gives me some sense of purpose because it means I am not only protecting myself, but possibly protecting others as well,” she said, according to WMTV 15 News.
Prosecution and Defense Clashed Over Brown's Age
Assistant District Attorney Alex Goulart, a veteran sex crimes prosecutor within the Rock County District Attorney's Office, served as lead prosecutor in the case, per Big Radio. The office is led by District Attorney Jason Sanders, who took office after his November 2024 election, according to Ballotpedia.
Brown's attorney highlighted that Brown was only 17 at the time of the assaults and asked the court for probation instead of prison time, WMTV 15 News reported. That argument touches on a quirk of Wisconsin law: under the state's Juvenile Justice Code, defendants who are 17 years old at the time of an offense are automatically prosecuted in adult criminal court, without a judicial transfer hearing, according to the Milwaukee Criminal Lawyer firm. Wisconsin is one of only three states nationwide — along with Georgia and Texas — that automatically routes all 17-year-olds into the adult justice system, according to the Wisconsin Justice Initiative.
No Parole Under Wisconsin's Truth-in-Sentencing Law
Because Wisconsin operates under Truth-in-Sentencing rules, Brown will serve the full 20 years of initial confinement in custody before beginning his 13 years of extended supervision, with no possibility of parole, according to Grieve Law. First-degree child sexual assault is classified as a serious sex offense under Wisconsin Statute § 939.615, meaning Brown will also face mandatory sex offender registration once released, per Chirafisi Anderson, S.C.
Between his May conviction and his August 7 sentencing, Brown remained held in the Rock County Jail, Big Radio reported. He was found guilty on all three counts on May 6, closing out a case that spanned nearly a decade from the initial 2017 abuse to this month's sentencing.
