They've been combing through test results for a week, but the family of David Hartley tells 7NEWS they don't believe it was his body found in a lake on the U.S.-Mexico border.Hartley's wife, Tiffany, said Tuesday there were no DNA tests and no forensics tests performed by Mexican authorities on the remains. But, she said the height of the skeletal remains found was much shorter than David, the clothes didn't match and there was no bullet hole in the skull."I mean this gave us a little glimmer of hope that, yes, possibly one day David will be brought home," said Hartley. "And we truly believe that still. We still believe that God is going to find a way to bring him home. We don't know how, we don't know when."Hartley has always said David was shot and killed by Mexican pirates in Sept. 2010, when the two of them were jet skiing in Falcon Lake on the border.The Hartley family filed a lawsuit against the government for the way it handled the investigation, it is still going through the courts.
