AL Scratched Intials on Ring Help

(Indiana)

If I were a young girl and somebody very important to me gave me a ring as a gift I might scratch that person`s initials on the ring. Or, if I was giving the ring as a gift I might scratch the recipient`s initials on the ring ( a kid`s way of giving a monogrammed gift).
It`s very common for kids/young teens to do that sort of stuff. I would definitely stay focused on the 2 rings in this investigation. My gut tells me it`s likely her parents/guardians were involved or her significant other. Is there any way to know if this girl had been pregnant at the time she died? It`s hard for me to imagine that an adult woman would wear a defaced ring unless it was given to her from a child who defaced it purposely.
Maybe A.L. was a young child in 1970/71?
