A search warrant seeking the medical records of an owner of candy company Mars Inc. states that Jacqueline Badger Mars told a witness she fell asleep at the wheel just before she was involved in a deadly car crash.

The Loudoun County Commonwealth Attorney's Office says Mars was served Tuesday with a summons for a reckless driving misdemeanor charge. The sheriff's office says Mars' Porsche SUV crossed the center line in Aldie, Va., on Oct. 4 and hit a minivan. The sheriff's office says 86-year-old minivan passenger Irene Ellisor of Huntsville, Texas, died at the scene.

The 74-year-old Mars, the company founder's daughter who has been ranked by Forbes Magazine as the world's seventh-richest woman, is set to appear in court Dec. 5.

A personal spokesman says Mars "regrets this tragic accident."
