Texas law enforcement reported that the monster had 3 gun shot wounds and the last one (to the head) was self-inflicted. Not to take away anything from the two heroes who shot and chased him (quite possibly preventing a worse killing spree); just reporting what I just heard.
One of the reports I heard said a witness saw the gunman approaching the church “in full gear”. And, apparently Mr. Willeford’s daughter got a good look at what was happening. So I can well imagine how scared Willeford (especially) must have been to go out there to take on a gunman in body armor, even if he (Willeford) had an equivalent weapon...
So, Mr. Willeford wounds the shooter anyway, then our good guys in a pickup truck chase after the shooter at speeds reportedly up to 90+ mph. (I suppose the adrenaline both helps and hurts.)
The third shot was because of the first too.
