JUNEAU COUNTY, Wisc. (CBS) — A 17-year-old McHenry girl has died in a snowmobiling accident in Wisconsin, authorities said.

Mallori Papp died Friday of blunt force injuries to her chest, the Juneau County, Wisc. coroner’s office said.  About 5 p.m., officers received a report of a snowmobile accident on a snowmobile trail near the town of Hustler, the Juneau County Sheriff’s Department said in a release. 

Papp, whom police say had been operating the snowmobile, was pronounced dead at Hess Memorial Hospital.

Hustler is in central Wisconsin, about 100 miles northwest of Madison.

Papp had graduated early from Johnsburg High School in the far northwest Chicago suburbs. Principal Kevin Shelton said the school will have counselors and social workers available next week for the teen’s peers to help them cope with the loss.

“She was a very positive presence at Johnsburg High School,” Shelton said of Papp. “She was an incredibly nice young woman. She’s truly going to be missed.”

An investigation continues, Juneau County Sheriff Brent Oleson said in the release.
