these people appear to have been in contact with the shooter at some point:

on further inspection it appears to have been a twitter argument, however two other individuals in the argument are @vrilsols and @totenwache (very similar name to @totencord who the shooter followed and was in discord servers with, I'm not sure what toten could mean on these twitter spaces I'd appreciate if someone could provide some information)

The second account seemed to have replied to him with the word "Andrew" but again, I'm not sure what this could mean especially without the context
upon further investigation the @totenwache account appears to have an alt called @testsite2271 and appears to be a lesbian in a relationship with @brunnh1ldeee, from a basic look of her account she appears to be going for the "I'm a based nazi egirl uwu ^_^" aesthetic and seems to be a fan of the shooting on the basis that he's a black guy killing himself

they also seem to be some sort of agp fetishists, making trans "jokes" and interacting with an account called @SataniaIsMyWife which, from looking through that account, appears to be a homosexual femboy

the "Iris" account identified earlier in the thread had this to say after the Samantha Rupnow shooting:
there was also an example of a skibidifarms user saying that groidcell should be unsuspended:
there was also this account in a conversation involving groidcell praising Samantha rupnow:
there's also this account @whitegermanboy asking for his discord, perhaps they were friends?

another account defending him:

screenshots from his old account:

another instance of Lulziness interacting with him:

two people who were allegedly mutuals with the shooter:
the account appears to have referenced satanism in replies to the shooter
he also appears to have interacted with nitrogen and is followed by him on his current account l1near (@noncognitivist)

an account replies referencing Dylan roof and Samantha rupnow:

another two accounts that interacted with him, one claiming to have been in a gc with him:
a user in the past has also replied to the shooter with references to anders breivik

and he was in a thread with an account named @sinister_sh00t (likely a reference to o9a)
