Crystal Lake Police responded to reports of a large, teen party in progress at 1748 Andover Lane on Saturday night, Oct. 13.
According to police, about 100 kids were at the home, which is owned by Brian T. Bianchi, 37.
A DJ had allegedly been hired for what other witnesses said was a birthday party for one of the juveniles.
Upon police arriving at the house, the majority of the party-goers fled, said Crystal Lake Police Chief David Linder. However, evidence of alcohol was present throughout the house, he said.
Only 30 kids were left, and police officers administered portable breath tests to some of the teens. However, some parents refused to allow their children be tested, Linder said. As a result, no juveniles were charged with any offenses.
Bianchi was charged with one count of hosting a "public nuisance assemblage," Linder said.
The law states no homeowner can cause, permit, or host an assemblage of minors on their property where conditions are such that they encourage underage drinking and other criminal acts.
According to McHenry County public access records, Bianchi has an arrest history.
He was indicted Feb. 8, 2012, on one charge of aggravated domestic battery/ strangle (a Class 2 felony), one count of domestic batter/ physical contact, and three counts domestic battery/ bodily harm. He was scheduled to appear in court Oct. 2, and his trial has been continued, according to court records.
An order of protection was also filed against him in January, court records show.
The investigation is ongoing. More charges could be forthcoming.
Several parents from the Crystal Lake South High School community expressed concern about the event, noting several of the teenagers who allegedly attended the party also participate in school-sponsored activities and athletic programs.
