One thing that hasn't been mentioned: Leyden Road has been closed to all but local traffic for construction all summer. I know because we were researching Arvada and Colorado history and wanted to drive down it between Indiana and Hwy 93, but couldn't. It's closed beginning at Quaker and all the way to 93, and that was still true as of a couple of weeks ago (I was coming up 93 from Golden and looked, because I would have driven back that way just to drive through the canyon to get to my house).
I'm sure the perp knew that.
I also saw a news report that said 93 is closed in both directions near the area currently, so they are working much closer to Hwy 93 than Indiana.
And like Eesti, I'm just horrified. These are all areas that I regularly run and bike in, and all of it is just miles from my own house.
But even the earliest reports said they were a couple, so there was an indication from the beginning. It was equally clear that he was a suspect from the beginning.
That was Thornton--east side of I-25, nowhere near the Jeffco schools.
Again, there's nothing good going on when any school in Jeffco is on lockout. I've never seen them do it just because law enforcement is in the area. Yes, that's the story they told, but I'm pretty sure they were worried about someone entering the school while they canvased, whether because they were flushed by law enforcement or for other reasons.
