If they can peg down the timeline of when the first person noticed the sign, and the explosion happened by 9pm... they should have a really good window to check surround area cameras from stores, houses, traffic cams, etc.CrawfordAg said:
The latest bomb was set up in an upper middle class area. Have a friend who lives a couple of blocks away and they said the following in a text this morning.
"The explosive was attached to a sign that was placed there between 7:30 - 8:30. It read "Drive Like Your Kids Live Here" and had a trip wire attached to it. When the guys rode past on bicycles, one of their legs brushed the wire and the device detonated. Nails and other objects were everywhere...it was tragic"
That's a 2 hour window. I'd like to think they'd be able to do something with that.
