I only have that one photo, and don't care to run down further photos or stalk her socials, but I have a fair amount of experience with lacerations and bleeding, and normally by the time blood has dried like like it is on her nose and cheek, it's not that red. Blood turns darkish red/brown pretty quick. Her make up is also remarkably un-smeared and un-teary for just having been beaten to the ground.
I sure hope she hasn't decided to fake something for clout or to let her pivot to anti gun activism, but I'd need more than that pic from her facebook to give full credence to her story.
MPD has confirmed that her car was taken from her house and later abandoned, for what that's worth.
