Many times LE does not say their suspect is a suspect. Rarely do you hear police say someone is an out and out suspect
Police had to have probable cause to get a search warrant for RL house.
We really know nothing other than the police, at some point, had enough evidence to get the search warrant meaning police had a reason to suspect, at the very least, RL knew something.
And since then they have said he is not a suspect , so yes they may of suspected him but that doesn't mean he has not now been cleared hence "he is not considered a suspect"
