U.S. Rep. Sean Casten’s daughter was a seemingly healthy 17-year-old teenager when she died in June from a “sudden cardiac arrhythmia,” the suburban congressman’s family said in a statement Friday.

“In layman’s terms, she was fine, and then her heart stopped,” the Casten family said. “We don’t know what caused the arrhythmia, and likely never will.”
