A new witness to Michael Brown’s shooting has emerged–and she’s also got new amateur video from Saturday in Ferguson. Her account of what happened corroborates what Dorian Johnson says he saw on Saturday.

Tiffany Mitchell told KMOV News 4 that she saw an officer inside a police vehicle wrestling with Brown through the car’s window before a shot rang out. That’s when she says that Brown began running away. Mitchell says the officer fired again and Brown raised his hands in the air before being fired upon until he was killed.

"The cop just continues walk up on him and shoot him until he goes all the way down," she recalls. Mitchell also has new video, taken from her cell phone.

Mitchell has been dealing with the trauma of witnessing Brown’s shooting and says that she cries herself to sleep as a result of what she saw.
