A juvenile was arrested on May 10 and charged with attempted first-degree murder in connection with an attack on a Lyons Township High School student last week that left victim severely injured.

The victim remains in the hospital receiving treatment, according to an email sent to LTHS families. The extent and type of the injuries have not been revealed, but an email sent to the press and LTHS families described his injuries as “significant.”

The juvenile arrested May 10 is the second person charged with the attack. Last week, LaGrange Police arrested 18-year-old James Hernandez Jr. of Brookfield., an LTHS student, and charged him with misdemeanor battery. Hernandez posted bail and was released.

The person arrested Wednesday, whose age and hometown were not revealed, faces more serious charges. He was charged with both attempted first-degree murder and aggravated battery causing great bodily harm.

Other participants in the attack are apparently still being sought. Jack Knight, the village manager of LaGrange, declined to say whether the juvenile charged May 10 was an LTHS student or whether the juvenile remained in custody. However, the investigation into the incident is not finished.

“The investigation remains open and active at this time,” said a press release from the village of LaGrange. “This was an isolated incident and does not pose a threat to the community. The LaGrange Police Department has worked closely with school administrators throughout its investigation and will continue to pursue leads as the case develops.”

The attack occurred at approximately 4:10 p.m. on May 1 outside Exit 7 at LTHS’s North Campus and apparently occurred across Park Road from the school. A student who has seen a video of the incident said that at least one person was stomping on the head of the victim.

“The incident involved an altercation involving several juveniles and an adult, which resulted in the injury of two juveniles, one of whom was injured severely,” the press release stated.

Student hit by car seriously injured

Separately, another LTHS student was seriously injured on May 10 when he was hit by a car on Brainard Avenue as he was leaving North Campus. The student was hit east of the Vaughn Building.

“The student was seriously injured and transported to the hospital via ambulance,” wrote LTHS Principal Jen Tyrrell in an email sent to LTHS families and the press that night. “The La Grange Police Department is currently investigating.

“As more information becomes available, we will share that with our community.  At this point, we are unable to share specific information.”
