I think one big factor that differentiates the Crime and Horror imprints would be whether or not the investigator/enforcer/criminal/etc, who we get to follow is in a frail mental state or involved with darker powers. If the protagonist's sanity is slipping throughout the narrative due to internal or external forces, it'd probably be a better fit for horror, if not, and the focus is more on the crime or case itself, without the investigator being too personally involved in it (including through projection of his own personality or past history), it'd probably fit more into the Crime section.
Obviously, there are clear points that move the story firmly into Horror, but generally, the less overtly spiritual the case, the better it fits into Crime. The detective, if a story has one, needs to be more detached. You'd immediately be able to place Holmes into Crime whereas investigator-type characters in Lovecraft's or Poe's stories would be an easy horror fit. Carnacki, too, would fit more into Horror, although the overlap to Crime is there, simply due to the subject matter and way the character is presented.
Crime can deal with Chaos just fine, I believe, so long as the influence of the case's Chaos presence doesn't reach too deeply into them.
I think French's Covenant-related audio dramas would be a good fit for Crime, too. It wouldn't surprise me if they were getting a Crime-labeled Ianthe anthology once they got enough of those out.
