CHICAGO — U.S. Rep. Sean Casten’s 17-year-old daughter died in June of sudden heart failure in the family’s Downers Grove home, the congressman said Friday.
In a statement released Friday afternoon on Twitter, the two-term Democratic congressman said Gwen Casten “died of a sudden cardiac arrhythmia. In layman’s terms, she was fine, and then her heart stopped.”
“We don’t know what caused the arrhythmia, and likely never will,” Casten said.
