This my idea, not the most cleverest but still works and funny:
First try to get as much info on your victim as possible, when your set, call your victim under the pretext of being an you officer or some dective with the local law enforement agency in your area. Tell them that a local family member died, make up how they died, go nutz and be creative.
"Excuse me, is this Mr. Smith?"
"Yes it is, who is this?"
"This is dective Robert with ??PD, I'm sorry to disturb you but your daughters body was recently found nude in front of a porno shop. Apperently someone stuff 15 dildos in every crevce in her body and her body seems to have been covered in a white substance we believe to be semen. We believe this to be a orno film gone bad. Sorry that I had to tell you this"
"But she's only 14...*sobs*."
"Good day sir".
Or whatever you can think of. If you decicde to do this or something along the lines, please give me some credit or shoutout to "Illuminati". Thats all I ask unlike some jerks who will go mad over credit. Anyhow, good luck.
