A hellhound in an upscale neighborhood? That's like hearing Paris Hilton keeps St Bernards instead of that little lap dog. It's throwing off the player's mind set. You wanted the stuff to catch their attention as the clue right? They see nothing wrong with the military/runner gear because of the dog.
Look if you break into the home of the RL rocker Prince and found a bunch of sex toys and S&M gear you wouldn't be surprised because that is the image he puts out. Find the same stuff in say, Carrie Underwood's home, when she has such a clean image, and it will be a clue.
You need to refocus the team's attention on the man's 'hobby room.' Have them casually mention it to the wife and have her say 'what are you talknig about?" "No I never go in the basement, why would I, that's what I have a maid for." That way you can leave some clue on the work area, like an outlay of the yak casino tucked into a book about katanas- yeah a real book, what the frak? or the maid, didn't she mention that, knew all about the hobby room and "wondered why he got upset when I cleaned in there."
Beating the thugs is no good, they don't know anything. They are not high enough up the chain. They probably aren't even Yak's themselves just muscle or wanna bees. They become a link only back to their fixer. Draw on pulp detective stories here. "Serious man don't hit me know more. I don't know nuthin'. This guy just hired me an' Bertie to put the grab on some suit, you know."
A little more pressure and the team learns how to contact the Johnson-after all once they grabbed the guy they have to know to where to take him and when they meet the thugs Johnson they can TALK, ho knows maybe the Yaks decide to hire the runners to get the sword back even negoiate to let the idiot live owing the yaks a favor. So

2K from the wife, :nuyen:10K for the sword from the Yaks and you develop new contacts with the Yaks.
How to approach the mob? The husband woud have figured this out before hand. You don't plan the heist without planning resolution too. OK maybe you do but that's stupid. And it's your call as to what this guy is. It will be easier if he's that dim because he's still out there if it's planned he's already gone. The fact he had to go on the lam implies that he's the dim bulb planner.
Odds are he probably tried to just walk into a known mob hang out and asked stupid questions and got the ol' heave ho from the made men who were insulted by him "Hey I'm looking for some real connected guys."
"You mean electricians?"
"No, I mean
connected guys. dig?"
"I don't know what you're talkin' about chummer, this is just a bar."
If the runners have a mob conact, maybe he saw the exchange. - shown a pic "Yeah I remember him. Gino pitched him into a dumpster behind the "High 5" I think he got out 'fore the city picked up."
Then you figure the husband's getting desperate for funds and to make contact. Should be easy to go from there, the dope is probably drawing from the bank account and being a joint account the wife can see where. "Oh yeah he checked into a coffin motel at ____"
Then it's a race between main Yak thugs who have their own resources and the team, potentially hired by the thug's Johnson, a subcontractor.
All this assumes the group can't do a ritual spell search for the husband. If they don't think of it, the yaks did.
How does this help?
