I have a photo of that tombstone as well. It is also on postcards. I was born and lived in AZ until three years ago. My family had always thought we were related to Red. They robbed a Goldwater's store and a pregnant women was shot a killed. They hid out for awile, Red with some Native Americans but eventually all were catured and hanged. It was known as the Bisbee Massacre if you would like more information. That is also the reason I checked into a bed and breakfast under the name "John Smith" while staying in Bisbee some years ago.
