He was a murder suspect, someone pointed him out to her at Walmart during her shift and she gave chase on foot. He turned around while running and shot her.
While she wasn't targeted because she was a cop, this case does bring to the light the issue of whether officers should pursue a suspect by themselves or wait for backup. In a lot of these police shootings a single officer will try and catch a suspect and when the two are alone there is a shooting "incident."
Do you let a murder suspect who is listed as "armed and dangerous" walk away and risk not being able to find them when you have backup or do you pursue the suspect and risk having a deadly altercation. If an innocent person is killed because he was able to continue with his fukk shyt that leaves the city/county/state open to legal action. It is dicey all around.
Personally, I don't think female officers should be put in that position but that is another debate for another time.
RIP to the officer and her family. I bet the killer has a few bodies out there so hopefully this will lead to closure for some other families.
