Antifa spotted her and she was most likely never killed. I thought like you did before, but nowhere in those videos does she look like she died. Apparently, according to some you are not even allowed to question anything about her dying.
Whatever the media or Dems tell you if you look 180 degrees the other direction is usually where you find the truth.
Numerous media reports (including NYT and WP) reported she died at at a local hospital after being transported there by ambulance. You may question that, too. I wonder whether she was DOA and pronounced dead after arrival or was still hanging onto life and died in the hospital, but that really does not matter.
You are welcome to believe what you believe. I understand trust in the media and our institutions has broken down, and for good reason. I sympathize with your distrust. I happen to believe she is dead. It’s a free country, and we are both free to believe what we believe.
