It will take two weeks to find out why a driver lost control of her car causing an accident that took seven lives, including her own. An S.U.V. lost control last Sunday on Interstate 20. It crossed the median and hit a mini van head-on. It will take a "reconstruction team" another two weeks to determine what exactly happened on I-20. The two car collision killed seven people, including three children. The only survivor, a three year old child, remains in critical condition at a Dallas hospital.
