I've looked at Betty quite a few times and wondered if she could have been Elizabeth Evans. She was 39 when she went missing in 1978. One of the stories that TR told about Lisa's mom was that she was an older woman and they had been concerned that Lisa might be born disabled. He said they had planned to bury her next to an ant hill if she was but she was born perfectly healthy. He was not talking about Lisa's real mom, Denise Beaudin, since she was only 23. His first wife was also young, so he wasn't talking about her. And the woman in the barrel is estimated to be in her 20's at most as well. So who is the "older" woman he was talking about? Maybe Elizabeth Evans was older?
As for Denise Daneault it does seem like such a huge coincidence that she only lived a few houses from a SK and now they are searching on Kimball St. As of right now, however, they are saying there doesn't seem to be any connection:
