I think that if it were possible that he were a victim, the authorities would not be so sure of themselves. The ultimate tell will be the ful chemical autopsy. There was no sign of struggle on Chris. Therefore, he must have been first poisoned and then hung, or hung himself. If the autopsy turns out to be negative (meaning there are no foreign agents in his system... aside from the roids he was shooting) then i would assume the investigation would change directions. At this point, however, it seems quite clear that he murdered his wife and child. It's not as if he was some saint. His wife had filed for legal protection from him before.

EDIT: Also, if he was the one to strangle his wife, DNZ analysis, ginger prints, and the size of the marks on her neck will all prove his guilt.
