I can't speak to her upbringing/schooling in her family of 7 siblings (I think), but going way back to the first days Erin was missing, I saw her 'biological dad' and his partner in a MSM video interview where he stated "this girl just needs to be brought home" and seemed quite choked up. IIRC, Erin was adopted, and didn't know her biological father (the man in the interview), and her biological mother was said to be in jail/prison. Not sure if true, but I thought she was adopted by her mom (Lore Heavlin) and her husband at the time, and then they divorced and her mother remarried her current husband when Erin was young. So Erin's parents who came to 29 Palms initially when she went missing were her adoptive mother and her current husband (Erin's stepfather). Her parentage and upbringing are not relevant to what happened to Erin, IMO, just commenting on what IIRC her familial background was. Obviously her family loved her and that is all that's important, whether she was homeschooled or adopted or anything. IMOO
