I'll tell you why I suspected him.
When its a murder mystery, its usually the last person you suspect and in this case it had to be someone the show could do without, that either means someone's contract is about to be up OR a newish character that was never meant to stay around long anyway.
OR certainly someone who could claim insanity or something like Emily did after she had kidnapped and chained up Dusty.
If Evan Walsh Jr hadn't been the one to do it, I couldn't make sense of why his character was introduced to begin with.
