AUSTIN -- Police do not know what direction the bomber traveled for any of the crimes.
We started at first explosion site, 1112 Haverford Drive. The even-numbered house sat to the left of us in the middle of the block. Plywood still covered the doorway.
From the first house location to the second explosion, a route of 13 miles was the fastest. It headed south on I-35, turning west on 290, then south on 183 towards the neighborhood near Martin Luther King Jr. Blvd.
We took a shorter route: 11 miles down Dessau Road to U.S. Highway 183. The second house at 4806 Oldfort Hill Drive, another even number, also sat in the middle of the block.
A newspaper was in the driveway. The front-door welcome mat tucked behind bushes. A sign on the door warned "do not enter.” Cleaners were using thermal fogging.
The third explosion location was half the distance from the second house. Half the time, too.
We traveled down Highway 183, turning west on Vargas Road. Again, the house sat middle of the block. Again, the even number, 6706 Galindo Street, was prominent on the house. Bars on the window and the security warning sign out front gave the only indication this neighborhood wasn't like the other two.
Now we wait to learn more about the fourth neighborhood. The roads were blocked at all entrances Monday afternoon. It's on the west side of Austin.
The home was about 11 miles away from the third location. We headed south to Highway 290. Then, drove west until we crossed MoPac and entered Southwest Parkway.
The shape is now looping around Austin, but to assume a path would be premature. The only person who truly knows the plan is the criminal(s).
