Suburban teen dies after being found unresponsive at Lollapalooza

CHICAGO — A teenage boy has died after being found unresponsive on the Lollapalooza grounds Sunday night.

According to a family friend, 16-year-old Evan Kitzmiller attended all four days of the  festival after buying a pass with money he made working at a Mundelein car wash. On Sunday, the final day of the festival, Evan was found unresponsive on the 300 block of East Randolph Street around 7 p.m.

Pierce Roberson says he saw Kitzmiller receiving treatment from rescue workers, and he appeared to be having a seizure.

"As they're tending to him, I walked a little closer and I see him shaking and convulsing," Roberson said by phone.

Kitzmiller was transported to Northwestern University Medical Center, where he was pronounced dead.

Melissa Kitzmiller, the teen's mother, told the Chicago Tribune he kept in contact with her throughout the festival and had last checked in around 6 p.m. Sunday. She said she believes Evan possibly had a seizure, but he didn't suffer from epilepsy so she didn't know what could have caused it.

Friends attended the show with Evan, but said they don't know what happened either. An autopsy by the Cook County Medical Examiner's Office proved inconclusive Monday, and further studies are underway.

Lollapalooza organizers released the following statement:

“We are saddened to learn of the death of an individual who attended Lollapalooza on Sunday. The individual’s family and loved ones are in our thoughts during this difficult time. We have no further information at this time.”

Evan would have been a junior at Mundelein high school this year, where school administrators say he was on the honor roll. The school says it will have counselors on hand to assist students during the school week.
