Wal-Mart heiress, Alice Walton, spent her 62nd birthday in jail following an arrest for driving while intoxicated (DWI) on Oct. 7.

Walton's attorney, Dee J. Kelly, told the Weatherford Democrat that she accepts full responsibility for the incident and deeply regrets it.

Returning home after a birthday dinner in Fort Worth, Walton was stopped on Interstate 20 by Department of Public Safety trooper, Gary M. Rozzell.  She was driving 71-mph in a 55-mph construction zone.

Through an investigation at the scene, [Walton] was determined to be intoxicated during a field sobriety test, Rozzell said. She refused to take a breath test.

She accepts full responsibility for this unfortunate incident and deeply regrets it, Kelly's statement read.

Walton, the daughter of Wal-Mart Stores Inc. founder Sam Walton, spent the night in the Parker County Jail and was released Saturday morning after posting $1,000 bond.

Though the money might not be an issue for the 10th richest person in the U.S., according to Forbes Magazine, worth more than $20 billion, her driving seems to be.

According to ABC, Walton was convicted of a DWI in an Arkansas car crash in 1998 after her sport-utility vehicle flew off a road in Springdale. Her blood-alcohol level was .16 when it was taken at a hospital after the crash.

Walton was also convicted of driving under the influence in a 1989 accident that led to the death of a 50-year-old woman.

No charges in her DWI arrest Oct. 7 have been filed.
