That was also my question, as well. Iirc he was detained at the station for questioning earlier that day, though not sure exactly what time (I would MOO it was sometime in the early afternoon, since the Thayers stated in their interview that he left their house late morning to pick his father up at the airport) and he wasn’t actually under arrest until 11:30PM Wednesday night. I am an HR professional and it seems odd that there would be an HR rep on hand at that time of night to render a termination. Hence leading me to believe he would have been termed during normal business hours. (MEO). Which also leads me to further question his reason for termination. I plan to try to do further research into their policies and procedures and code of ethics to see if he may have broken a policy by being a suspect, since there was no reports that he admitted to anything until after he spoke to his father that night. I’ve read other speculations on his term reason in other forums which have me interested on another possible motive which could lead to signs of pre-meditation.
