@Ella-vibe I'm sad we probably won't see True Identities more, but I can respect your decision. And if someone gets mad at you and is rude about it...
I will inject a large amount of insulin under their tongue and they will die of high blood pressure. I will then take their body at least two hours away from the murder scene. I will dig a twelve foot hole. I will put their body in the hole. I will bury the body 2/3rds of the way. I will then place an animal carcass on top of what's already been buried and finish filling up the hole. If the police figure out that forest is where the corpse is, the dogs will come sniffing and only find an animal carcass, and the police will assume that's all there was. If they still find the body, insulin doesn't even appear on a standard toxicology report. If the police test specifically for insulin, they'll find it and assume the person had an undiagnosed diabetes.
Don't mess with my honorary cousin or else, people
:D
