The kid got a 26 minute lead on the cops during a 5 mile high speed chase? If they were chasing him they would have been on top of him at 11:29!
I have not seen any confirmation that there was a chase. There was a BOLO alert. After leaving vehicle, he shot at a couple people at a funeral home near the school. They called 911. Seems like that was first confirmation of his location.
Of course, Texas DPS could change the story again.
