Was Cayler Ellingson wearing something Q-themed when he was murdered?

Anybody explain how this motherfucker who killed him knew he was a Trump supporter? Heard/saw in passing somewhere they didn't know one another. In past attacks on Trump supporters, it's been said/known the person had a MAGA hat or a sign or something. Assholes now are emphasizing the motherfucker believed he was in a MAGA extremist group. Oh really? Did the poor kid have a Q or WWG1WGA shirt on and are the craven bastards being this vague on purpose to prevent chatter/sympathy?
