In that transcript, he attributes GZ saying that he left his keys in his vehicle when describing where it was parked. The operator was talking over him, so many transcripts don't have this statement, but when I listened to the call, it sounds like thats what he said.
I've heard that before, but I've never put any stock in it.
I can't make out what Zimmerman was saying at that point, but I think he was giving the make, model, and color of the truck. He said he did that a few times in the SPD interviews, just at that point, as the final part of the directions he gave.
In that context, it makes no sense that Zimmerman would say the keys were in the truck. That's not something the officers could see at a distance, to distinguish the truck from the other one parked nearby. I also see no other reason Zimmerman would want to give the dispatcher that information.
I don't know that it has been determined that the key on the flashlight keychain fit the Ridgeline, but the key is described as 'Honda brand name' in the evidence log (5/184
ETA: Leaving the key in the truck would be a dumb thing to do, with a suspected thief in the area.
