WAUKEGAN, Illinois (AP) -- A 10-year-old girl who collapsed at an amusement park died of a congenital heart condition, a coroner said Thursday.

Lake County Coroner Richard Keller said the roller coaster she had just ridden did not trigger the heart attack that killed her, the Chicago Tribune reported on its Web site.

Jaclyn Silberman of Arlington Heights collapsed Wednesday night as she ran to rejoin her family after exiting the ride at Six Flags Great America in Gurnee, Illinois.

The girl, who police have said had a history of heart trouble, was pronounced dead about an hour later.

Police in Gurnee, about 40 miles northeast of Chicago, are not investigating, Cmdr. Jay Patrick said.
