Mike, sue her in small claims court. Leaving the cues in her house with her having knowledge of them being makes her responsible. In small claims nobody needs a lawyer and it costs you about $10. Sue her for full replacement value. Argue your case that she knew they were there, don't mention the shady characters.
The 3 ways to win are as follows:
1 she gets scared and just offers to pay you off ( not likely).
2 she is stupid enough to forget the court date or not show up. Either way the Plaintiff, you, win. They do not reschedule in small claims court and the Plaintiff wins by default.
3 The judge rules in your favor because you can show that you had brought them there. Anyoneelse on you side know thery were in the House? Or the judge is an ex sate straight pool champ and rules in your favor with a wink.
P.S. The cops will do NOTHING. Just file your case and await the trial date. I had a kid steal my cue once anhe didn't come to trial. All I did was tell the judge my story and the value of the item and he had a judgment placed on his earniongs. Most locals you can sue to $3,000 value.
Otherwise go covert on her ass!!!
