(CBS) — The 31-year-old daughter of Illinois Senate Republican Leader Christine Radogno has died.

Lisa Radogno was a scheduler in the Washington office of U.S. Sen. Mark Kirk.

She injured her arm and leg in a hit-and-run in Washington back in May. It’s believed that could be what triggered a blood clot that claimed her life Wednesday night.

Described by close friends as “always smiling,” she was on the phone when the person she was talking to detected a problem and called 9-1-1. Sen. Kirk was emotional remembering her on the Senate floor Thursday.

“Lisa Radogno was one of the brightest lights of my Washington D.C. office,” he said.

Radogno was such a huge White Sox fan she had the team logo tattooed on her ankle.

Her mother’s Facebook page was filled with condolences.

“We cannot begin to imagine your pain, only share our love,” state Rep. Kay Hatcher said.

Sen. Radogno and her husband flew to Washington Wednesday and were at their daughter’s bedside when she died.

The elder Radogno is a lawmaker based in Lemont.
