While the relevant part you point out had been more than once the subject of speculation here, simply because basic descriptions of suspects in the media (or names, when known) seem to be consistently left out of early accounts, waiting for confirmation or even a mug shot deflects a lot of the accusations the media are dodging. Of course, anyone possibly from the left shooting up anywhere doesn't fit the narrative of 'white-christian-rightwing-racist-homophobic-MAGA-neonazi'-"hater", so those stories get buried in a heartbeat.
I won't assume a demographic, but past experience generally indicates that a Caucasian shooter would have had that fact mentioned in the news.
This incident sprang from an argument at a birthday party, and the fact that 28 were injured and 4 killed means there was a lot of shooting going on in a 50 person party, and and it is highly likely that a more comprehensive description of the suspect(s) could have been issued. It's also likely that the police know exactly who they are looking for.
Nice wordsmithing there, I guess. The more relevant point is that no description was given of the killer. That means its a negro. This has become axiomatic. If they refuse to say, it's an african. This is due to this sick pity that people in so called news and so called law enforcement overtly express for negroid violent criminals. "Dey jus caint hep demselve". This is sickening and suicidal.
Unlike many do-gooders, I don't see negroes as rescue animals. They are the people with whom I grew up. I know they are capable of not being subhuman pieces of shit. The evil bigots among us call my attitude toward them "racist" because I see them as fully human while they consider that cruel. Just like when they fawned over Brakabama the mulatto because he didn't sound like Uncle Remus when he spoke(Brak has since altered his speech), they consider a negro who isn't climbing a tree for a banana something akin to a bear riding a bicycle. A miracle. Scumbags.
