Sounds like she told multiple people in the neighbourhood when drunk. I read many articles but I think only 2 of those mentioned that it was neighbour who sent a tip and only in one of those two name of the neighbour tippster was stated which I was quite shocked about. I can't find that one anymore, so maybe I imagined it or they quickly pulled it out.
Only after the tip, when police quiestioned exhusband, he confirmed it was valid information.
Going through all the articles again all of them mention that it was medical clinic and one call it hospital facility, in McHenry, Illinois. None state the name. Not sure how big McHenry is or how many clinics would be out there at that time.
Maybe easier way to find the name would be to look through Linda's info profiles - job history or her Linkedin. Or as registered nurse, her history and where she practiced in that time frame should pop up on some kind of license.
