You're not that well informed obviously if you didn't know that Julie Mugford obtained pills on Jeremy's behalf as part of his plan to drug everybody and then burn the farmhouse down. Such a nice boy!
I don't think so. If any pills had been obtained pre-tragedy,they'd have been experimented with as in a " drug buzz ". If I remember rightly,JM " needed " the so-called tranquilisers because she was suffering from stress with her work. Jeremy was officially offered Valium post-murders.
If anyone was a headworker here it was JM !
