Terrible and intriguing flyer

This flyer appeared at my Max stop this morning.  What an unfortunate story.  Martha Marie Morrison was murdered in 1974.  Her siblings assumed she was reported missing, but she never was.  I’m curious about the details of the story. As a 17-year-old she was already living with her boyfriend.  She also suffered from psoriasis, which is something we have in common. This Wikipedia page has more information.  It sounds like she had a hard life.
