David Hartley and his wife Tiffany

Investigators in America and Mexico are trying to figure out where the body of American tourist David Hartley could be.  Authorities say David was allegedly shot and killed by Mexican Pirates on Lake Falcon when he and his wife Tiffany crossed over into Mexican territory.  Tiffany says they were taking pictures and jet skiing together on the water when gunfire erupted and David was shot in the back of the head.  Tiffany said she had to make a life or death split second decision after trying to save her husband when she realized he was too heavy to move and load onto her jet ski.  Tiffany claims that as she was being fired upon, she had to race as fast as she could back to American waters.  At least one identified witness has come forward and claims he saw Tiffany flying through the water on her jet ski as she was being chased by a boat of men.
