A Crystal Lake South High School dean, who is also a Prairie Ridge High School volleyball coach, was arrested for driving under the influence and causing an injury crash while she had two children in the car.
The Crystal Lake Police Department and Crystal Lake Fire Rescue Department responded around 9:15 p.m. last Friday to the intersection of Route 31 and Three Oaks Road for a vehicle crash with injuries.
Crystal Lake Deputy Police Chief Thomas Kotlowski said the investigation showed the at-fault driver in the crash was Hilary Agnello, 43, of Crystal Lake.
Agnello was suspected to be under the influence of alcohol at the time and arrested by officers, Kotlowski said.
Kotlowski said at least two people were transported by ambulance from the crash with minor injuries.
Agnello had two juveniles in the vehicle with her, Kotlowski added.
Agnello was charged with driving under the influence, two counts of child endangerment, operating an uninsured motor vehicle and failure to reduce speed to avoid a crash.
A criminal complaint filed in McHenry County Circuit Court said the two children in Agnello’s car were ages 12 and 14.
An officer noted in a report that Agnello’s speech was thick-tongued and she had an odor of alcoholic beverage emitting from her breathing and field sobriety testing showed further signs of impairment.
The report said Agnello refused to submit to or failed to complete testing, resulting in a minimum 12-month suspension of her driving privileges.
Kotlowski said Agnello refused to submit to blood alcohol testing and a search warrant was obtained for blood samples, which will be sent to the lab for analysis.
Agnell is one of the deans at Crystal Lake South High School in District 155. She is also the girl’s volleyball head coach at Prairie Ridge High School in Prairie Grove, which is also in District 155.
Agnello was released from custody following her arrest and is scheduled to appear for her first court hearing in the case on June 10.
Court records show Agnell has a prior driving under the influence violation from 2017 and also has numerous traffic violations in McHenry County, including one where she fled the scene of a crash involving a parked vehicle last year.
