There was another case where a girl disappeared on her way home after getting off the school bus. The mother was so excited to be receiving money to help with the search but people began to suspect that she had something to do with the disappearance. She seemed to have little concern for the child. This was in 1982 or 83.
the Cherie Mahan case, I believe. She was never found.
Happened a year or two after a child disappeared from a shopping cart at the old South Side Giant Eagle location.
