Read the second to the last comment in the story. The Texas rangers investigated this too, so there may be more to come.
I did read that. I don’t see why it requires the Texas Rangers to arrest the former officer - the local police know exactly what happened, know it violated policy, and it was so egregious that they immediately fired him. I do not understand why an arrest wasn’t also done. I understand that they forwarded recommendations to the DA, but I see absolutely no reason why that former officer should not have been booked into the local jail. Let him bail out while the DA considers charges and the Texas Rangers continue their investigation.
