Cedar Park police say that based on evidence, including items found within the remains, they are "confident as possible without DNA confirmation" that the remains are those of Gordon.
Police say remains were found in two different areas of the Bastrop County property and remains were found in a burn pit.
"It is clear through the investigation, there were measures taken to dispose of the evidence," Cedar Park police say in a release. "We will not be able to confirm the identity of the remains until further DNA forensic testing can be done."
