Destinee Thompson was supposed to be on her way to lunch with her stepmother in August 2021 when Colorado police, mistaking her for a robbery suspect, fatally shot the pregnant mother as she fled in her minivan.
This isn't so clear cut, the police did try to ask questions first. They asked her to stop and speak to them, she kept walking and got in the car. They asked her to get out and speak to them, she refused. They broke the window (escalation) so she panicked and tried to drive away, smashed a police car behind and then drove forwards over the curb. At that point she's using her car in a very dangerous manner, so lethal force is potentially justified.
However the police shouldn't have escalated by breaking the window to begin with. They had her contained, she was no longer a risk, not until they escalated.
