true- but johnny followed the fella at high speeds- weaving in and out of traffic to keep up with him to report where the fella was going - and he did so knowing the killer had a gun
The Texan with the gun was not Johnny, but directed Johnny to follow the perp.
The man with the gun jumped in Johnny’s pick up and directed him. Johnny heroically obliged.
The man who fired the gun, ran the perp off, got Johnny to follow the perp, and held the gun on the perp (who probably bled out or committed suicide) until LE arrived.
This is according to Johnny.
The hero was the guy with the gun. We don’t even know his name.
