Discord was not used by Tyler Robinson to either plan the murder of Charlie Kirk or to hide the evidence … TMZ has learned.

A Discord spokesperson tells TMZ … “In the course of our investigation, we identified a Discord account associated with the suspect, but have found no evidence that the suspect planned this incident or promoted violence on Discord.”

The statement goes on … “The messages referenced in recent reporting about planning details do not appear to be Discord messages. These were communications between the suspect’s roommate and a friend after the shooting, where the roommate was recounting the contents of a note the suspect had left elsewhere.”

Authorities say Robinson’s roommate showed them Robinson had made “a joke” on Discord and then showed investigators the messages, which included “‘Tyler’ stating a need to retrieve a rifle from a drop point, leaving the rifle in a bush … and a message referring to having left the rifle wrapped in a towel.” Discord seems to be saying these communications were not on its platform … rather on a note that Robinson had written, off the site, to his roommate.

BTW … Discord says it has removed Robinson’s account.
