At some time between 5pm and 5.30pm, TM phoned GBC and following their talk about buying sausages ...... to drop off to his daughters at his Parents' address, etc, etc, TM stated "I suggested that Gerard should tell Allison that I was attending the conference. I then asked to meet with Gerard in an attempt to understand and discuss what was going through his head in regards our relationship".
..... wonder if TM did show up at GBC's house ... 'to meet' with GBC, and 'to tell Allison in person that she was attending the conference'..... unbeknown to TM's twin boys who she has said were usually 'starting the sleep process at 8.30pm'..... we know that Allison was alive at 8.28pm (on the phone to Olivia). Witnesses heard loud screams (female, it seems).
.... not saying that TM was involved in the murder of Allison; just that she could be avoiding saying that she was at GBC's residence that night.
TM left the conference at 3pm, and when her boys returned home a short time later ..."I told them that I was sick and went to bed". (Must have been badly in need of some sleep). JMO
