One of the people being interviewed mentioned that the search for chloroform was only done once and the person was logged in for under 2 minutes. Has anyone else heard that? That doesn't seem very damning. Casey could have looked at the picture Ricardo posted, wondered what it meant and did a quick search to find out. If she was plotting to use chloroform to kill her daughter, you would think she would spend a little more time researching it. I don't know if the person that just noted this has her facts right.
But there was more than one search though, wasn't there? As well as one that search "how to make cholorform" first mispelled and then spelled correctly.
