Holiday Hills Police Department releases deceased Harvard woman’s missing person report

The Holiday Hills Police Department on Monday released a copy of the Jan. 3 missing person report filed for Harvard woman, Michelle Arnold-Boesiger, whose body law enforcement recently discovered in a Roscoe storage unit.

Holiday Hills Police Chief Darec Kleczka previously denied the Northwest Herald’s public records request seeking the report, claiming he would need to check with the McHenry County Sheriff’s Office before releasing the document.

On Monday – just over a week after the Northwest Herald sent Kleczka’s denial to the Illinois Attorney General’s Public Access Counselor for review – the police department emailed a copy of the report.

The document provided to the Northwest Herald included redactions of names “to maintain the integrity of the open investigation,” Klezca wrote in an email.

According to the report, Arnold-Boesiger’s mother notified police on Jan. 3 that she had not seen or heard from her daughter since September. Arnold-Boesiger’s husband, whom she was separated from at the time, had not made contact with her since December, according to the missing person report. Arnold-Boesiger’s cellphone activity stopped on Dec. 14, according to the report.

The missing-person report also mentioned an “abusive boyfriend” who recently had been arrested in Indiana and accused of kidnapping his child.

The alleged boyfriend, whose name was redacted from the report, fit the description of 33-year-old Jonathan Van Duyn. Van Duyn has been in custody at McHenry County Jail since Dec. 21 on charges alleging he choked, bit and struck Arnold-Boesiger during a July 2019 dispute, according to public court documents. He has pleaded not guilty to those accusations and is not charged in connection with Arnold-Boesiger’s death.

Van Duyn and his attorney previously declined to comment.

Arnold-Boesiger did not have a vehicle and was homeless at the time of her disappearance, according to the missing person report.

Officers with the McHenry County Sheriff’s Office, Winnebago County Sheriff’s Office, Wisconsin Department of Criminal Investigation and Roscoe Police Department discovered Arnold-Boesiger’s body on March 2 in a storage unit in the area of Route 251 and McCurry Road in Roscoe.

Those who knew Arnold-Boesiger described her as a “family-oriented” person with a “big heart.”

An official cause of death has not yet been determined and requires further toxicological testing, Winnebago County Coroner Bill Hintz has said.

Officials have declined to comment on the death investigation or say whether they consider Arnold-Boesiger’s death suspicious.

No criminal charges had been filed in connection with the investigation as of Wednesday afternoon.

Anyone with information about Arnold-Boesiger’s death or disappearance should contact the criminal investigation division at 815-334-4750.
