I have also wondered on here about this being a revenge hit. Even though he was a pediatrician, there are situations where children die in hospitals from accidents or illness and the doctor gets blamed. Or it could have been a former patient that was left with some sort of permanent injury (guy was complaining about hurt ankle so he could have known he was a doctor).Could be the only reason IMO that he would have done it while the children where there and shot the kids before Dr Dumois. Revenge.
Sleuthster,
Yes,I think the hurt ankle ruse was directed ta Dr.Dumois because he was a doctor. LE stated that they went back and checked all of his patients' families. There does not appear to be that kind of motive there. No patients or their families would have had any reason to seek this kind of revenge.
