There were two vehicles involved in assassination attempt. One of them contained improperly armed IEDs. The other was the one used by Crooks to travel to the location.

Crooks could not have driven both vehicles to the location.

"Lone gunman".

Sure thing. Nothing else to see here.

Maxwell Yearick was unavailable for comments.

This may be simply inflammatory journalism.

Yearick was associated with a family business that made/assembled fireworks displays.
Still not enough info released by GOVT to be sure.
