A 12-year-old Barrington boy died over the weekend after falling off his bicycle, authorities said.
Jonathan "Jak" Kallas, a seventh grade student at Station Middle School, was pronounced dead at 5:40 p.m. Saturday, at Advocate Lutheran General Hospital in Park Ridge.
According to Barrington police, officers and fire rescue personnel were called to the boy's home at 3:40 p.m. Saturday on a report of an unresponsive male. They began immediate treatment on the boy and then took him to Lutheran General.
Police said an investigation showed the boy suffered a severe head injury while riding his bicycle in the 400 block of North Lake Zurich Road. The investigation confirmed that the death was accidental, police said. Police declined to say whether Jonathan was wearing a helmet.
An autopsy determined Jonathan died from multiple injuries from falling off his bike, according to the Cook County medical examiner's office.
Barrington Area Unit School District 220 spokeswoman Morgan Delack said the district is saddened by the tragic accident and additional counselors and social workers will be at Station on Tuesday to help students who need support.
"Our top priority is wrapping support around our students as they cope with the loss of their classmate and friend," Delack said.
A GoFundMe online fundraising page has been established to help the boy's family.
"On Saturday Jan 14, 2017 our son Jak Kallas (12) was being the adventurous boy that we knew him to be," the page's introduction reads. "While riding his bike with some friends he suffered an injury to his head. Within a few short hours the brain injury took his life. We have suddenly been plunged into the realm of having to adjust to the loss of our firstborn, how that will impact our family from here forward, and the myriad of logistical pieces to deal with his death.
"While we are confident that the Lord will give us the strength to sustain us through, we are also acutely aware of the financial burden Jak's medical treatment and burial will be," it continues. "If in this time you are inclined to support the memory of Jak's life with a financial gift, our family would be extremely grateful."
