Someone asked a few pages back what exactly did the Female Assessor ask OP. Sorry that I didn't see this question before now. I have transcribed the questions and answers:
FA (female assessor): Would you please confirm if the deceased in this matter had access to the alarm remote.
OP: She did my lady.
FA: And could she activate and deactivate the burglar alarm?
OP: I'm not sure if she knew how to but she would have been able to if she had the remote my lady.
FA: One last question. Tell me, I would like to know if the light in the toilet, if it was broken at the time of the incident.
OP: It wasn't working my lady.
This exchange happens beginning at 12:49 in the following video.
