ST. GEORGE, Utah — A 6-year-old Tucson girl trying to keep warm in a car likely died from carbon-monoxide poisoning because of a faulty exhaust system, authorities said.
The girl and her mother were sitting in the car after midnight Thursday outside an apartment building where the woman's son lived.
The girl began having seizures, and her mother ran door to door to find help. Her son apparently wasn't home.
They were taken to Dixie Regional Medical Center, where the girl died.
Her mother's carbon-monoxide level was "quite high," St. George police detective Jonathon McInnes said.
The mother was treated and released. Police would not release their names until family members could be notified.
The woman lives in Tucson and was on her way to Provo for a temporary job, McInnes said.

On Wednesday, "she hears a loud noise in the engine and pulls off into St. George, where she has a son," he said.
McInnes said he spoke to mechanics who tried to help her that day with the 1997 Hyundai Tiburon.
"Her intent was to get it fixed, but she wanted to try every option to get it under warranty," he said.
