Sieg left her home, without permission, after she had an argument with her mother. No further details about her disappearance are available.
The girl's remains were found in a field by a man accompanied by his dog. She was thought to have died within six months to two years before and was completely skeletonized at the time of discovery. No cause of death was determined.
In 2016, her NCMEC reconstruction was released along with images of a jacket found near the remains. Bea's mother noticed a resemblance between the pair and recognized the girl's clothing. The match was confirmed in June 2016.
