I wonder if this young lady might have had special needs and was tortured/murdered by her caregiver. It would explain why she wasn't reported missing. I also think most teen girls with a deformed ear would wear their hair down, covering the ears, especially in the '70s when that was a popular style. The fact that her hair was in a ponytail leads me to believe that she might not have been self conscious about the ear and/or might not have done her own hair. Just my $.02.
Two cents? I think this observation is worth
way more than that.
1978 was way before the building and population boom that later hit San Diego Country. Proctor Valley Road is some what isolated today, but in 1978, the surrounding areas of Jamacha, Jamul and Otay Ranch would have been small settlements surrounded by either real agriculture or real working ranches. Ranching would be even more large scale further east.
I knew somebody who grew up on ranches in the area as his father was a cowboy. He and his family would rarely leave the ranches as before the population boom, there were just not a lot of places to go. I also suspect that his school attendance could have been well, sporadic due to the needs of the ranches and other interests on his part.
He also told me that the ranches were not only remote, but that housing for the cowboys and their families was usually mobile homes in close proximity to each other. This could lead to community cabin fever and contributed to a nasty dispute between two branches of his family regarding a romantic relationship that half the family felt was improper.
With this in mind, I wonder if the victim was from a ranching family? Perhaps not the owner, but one of the cowboys?
This may have led to her wearing the pony tail as everybody on the ranch would know about the deformity and there would be less pressure to conceal it. She was also wearing overalls- clothing more associated with ranching and agriculture.
Likewise, if her school attendance was sporadic, it may have contributed to her not being immediately noticed as missing.
