I am Earl Wood retired deputy sheriff Buckingham Virginia. I also have a part in the "Doc Antle Story" that was just released, episode three. Mark Topping who worked for Antle ended up dead from falling 180 feet at Crabtree Falls, Nelson County Virginia in May of 1989. I am personally investigating this incident and encourage anyone who saw, heard, or know in any way "ANYTHING" about this please contact me asap anonymously! This is so important for the victim and his family members whom I have "NEVER MET". Let's do this together!! Thank you Earl Wood!!
