An Illinois teen died after running into a tree during a family ski trip at Tyrol Basin Ski and Snowboard Area in Dane County.

Kaitlyn Miller, 16, a junior at Keith School in Rockford, suffered head injuries in the accident Saturday in the Town of Vermont near Madison.

Elise Schaffer, a spokeswoman with the Dane County sheriff's department, said they received a call around 10:30 a.m. Saturday that the girl hit a tree.

"I don't know what I am going to do without her," Kaitlyn's father, Bob, said Sunday. "She was just that special."

She was oldest of four children - born 20 seconds before her twin sister, Kylee.

Funeral services were planned for Wednesday and her burial was planned for Thursday.
