Sleeping drug found in Kerry Kennedy's system

(AP) WHITE PLAINS, N.Y. - A court document says the drug found in Ambien sleeping pills was found in Kerry Kennedy's blood after her recent New York auto accident.

A urine test found no trace of alcohol.

The ex-wife of Gov. Andrew Cuomo and daughter of the late Sen. Robert F. Kennedy said a week ago that her doctors thought a seizure caused the July 11 accident. She said their tests found no alcohol, recreational drugs or prescription medication.

She acknowledged she told a police officer she might have taken an Ambien by accident instead of thyroid medication.

The document is a deposition from a toxicologist who analyzed the blood and urine. She said she found zolpidem, the drug in Ambien, in the blood.

A call to Kennedy's lawyer was not immediately returned.
