The Diving Computer of Gabe, Tina and Wade Singleton

We had a specific location on the ocean floor where tina was photographed. Tina's body should have been found on the wreck or adjacent to it, not 16 meters away from the wreck at a 90 degree angle to the currents. We investigated gabe's dive computer and his version in relation to it giving out an audible alarm when he first scended with tina. I honestly think that just prior to her death, she was fighting for her life. Police tested the dive computers of gabe, tina and wade singleton. They didn't take gabe's transmitter, which links to his dive computer. Apparently this would have given more information to police. There has been no explanation
