Keep in mind that the general rule of thumb on WS is that speculation must be based on "fact", where facts have been provided. In this case, facts are included in the
arrest warrant.
"Suspect Cortez drove the unknown male suspect to 1700 Cedar Springs Road. Once there, the unknown male suspect exited the vehicle, shot Complainant Hatcher and took several items of her property. The complainant died at the scene. Detectives were able to
corroborate the suspect's statement through witness statements as well as survellance video footage from the offense location."<bbm>
The above is about as straightforward as any statement can be.
We can speculate about other things: Was CC an innocent dupe? Who hired whom? Was this truly a random robbery? If not, what
was the motive? Did CC know the victim?
A lot of room exists for speculation. But in regard to the above, it stands as stated. The shooter was a man, driven to the scene by Cortez. Witness statements and surveillance video show these things to be true.
