He only did this in Concord, the peculiar and distinctive markings were not in any of the other attacks.
At two attack scenes but on all the screens.
I know this is a confusing subject but there were pry marks at many, many scenes (#15, #20, and one of the San Jose attacks had significant markings from the EARONS' tool) but Concord had a distinct scratching pattern that almost seemed like a signature or a note-to-self. The screens on these houses were very loose-fitting and no prying was necessary to remove them so it was a little odd. These were the first attacks in Contra Costa County so these in particular I believe were made to help him get the lay of the land.
The screens were loose fitting, but how did the detectives determine they were easy to remove? Did they use their fingernails to grab them? What if EAR was a nail biter, and he did not have his usual screwdriver to use as a pry bar? He could have used something to try to grab at the screen or to make a spot in order to grab the metal in order to remove it. Until I saw the entire set of evidence, I would not make judgements as to whether they we done on purpose or as a result of using "tools" necessary to complete the job.
Now, if the marks were at all the crime scenes, then they could be seem as attempts to mark his victims or used to get attention, but like I said before, he could have just tapped the glass to get a response.
This is the same method EAR used in some of the Sacramento attacks. There were numerous pry marks on screens, which would have to be removed by a burglar or prowler before dealing with the glass window or door behind the screen. EAR also pried wooden door jams. I think EAR wanted to choose the quietest point of entry and not one where he had to spend hours removing a door frame. Detectives were able to match some of the pry marks to exact screw driver models. I just re-read some notes that indicated in one case EAR removed the screen from a sliding glass door and then cut a small hole near the door track, that allowed him to reach in to remove the dowel that was set by the homeowner for security.
