I’m still not sure if it was pre or post mortem. From the evidence it’s hard to know for sure. If it was post, it was very soon after death (within 2-3 days) before she was dumped in woods.
I read in the timeline (though don’t think it ever made it into evidence because of hearsay) that she said to friends(s) in a joking way how you can knock a kid out- put her to sleep while you party.
I think that conversation was with a fellow jail inmate. Not sure though.
