I am back after a rough break! And to spill the tea, do NOT drink any tea from Caroline Grills.

A comfort killer is someone who commits murder in response to an emotional need for comfort or security.
Material gain and a comfortable lifestyle are the primary motives of comfort killers.
Usually, the victims are family members and close acquaintances.
After the murder of a close friend or relative, a comfort killer will usually wait for a period of time before killing again to allow any suspicions by those in close proximity to subside.
They often use drugs or poison, and most notably arsenic, to kill their victims
Trust no one.
