I never heard the story before so I thought it was a Mary Ann Cotton type of thing: <a href="https://en.wikipedia.org/wiki/Mary_Ann_Cotton" rel="nofollow noreferrer">https://en.wikipedia.org/wiki/Mary_Ann_Cotton</a><p>Definitely not the same case, in this case seems the deaths were rather unintentional, although consequences of "Mickeys" slipped in their food.
I’m getting a 404 error.<p>Seems it was pulled recently.<p>I read this article when it first came out. I’ve looked for it since but couldn’t find it.<p>Fortunately still exists on backup sites.<p>Thank so much for posting!
