Casey and her boyfriend, Thomas Steele, disappeared from Granbury, Texas on August 7, 2000. They were initially believed to have run away together, although they were good students and their families did not believe they would have left.

In December 2005, their remains were found in a rural area in Somervell County, Texas. The bodies were not identified until the following April. Thomas and Casey's deaths remain under investigation and the man who last saw them before their disappearances is being sought for questioning. She is a Caucasian female.
