For several hours NASA held out hope that perhaps the crew members aboard Columbia had been able to survive.
But on the afternoon of February 1, the grim reality set in here in East Texas as human remains were found.
In Plankland in Sabine County, what appears to be part of a leg was discovered earlier today. Right after Tammy White and her family heard the explosion overhead, two of her boys and a friend said they discovered the leg in a pasture next to their house.
When the boys told their mom, she went to investigate and confirmed that it was a leg and immediately called the Sheriff's Department.
There have been at least two other reports of possible human remains in San Augustine County.
Law enforcement authorities are securing areas where body parts have been found. NASA officials will determine where the body parts will be taken.
