There's Criminal Element, run by the same people who run tor.com, and with similar response times, judging by duotrope.
Mixer Publishing is open to crime and mystery stuff, too. Apparently Scout & Engineer is also, if i'm reading their guidelines correctly (which i'm probably not, because they seem excessively fond of large words that don't mean a helluva lot). At least they reply quickly.
Over My Dead Body is a crime/mystery only venue, but they want queries first.
There's also Washington Pastime, Strand Magazine (long response times, iirc), Untied Shoelaces of the Mind, Short-Story.Me.
