To catch a thief - how do I do this?

Several days ago someone stole a pushmower I truly love. Only thing I've ever bought new. It's a very distinctive mower I slaved away to buy.

I hid the mower out of sight in back yard and was only gone 2 hours to attend to an emergency. Came back to cut grass and it was gone.

Made police report w/serial # and detailed description of this unique mower. Called every pawn shop within 20 mile radius an the surrounding small town police departments.The suspected individual comes by my house religiously 5-10 times per day - but whenI asked about the mower, he has not come around my home once. I did not accuse him of taking it. However, he is known to do such things as he is a "landscaper" not one neighbor likes.Passed by him in places we both frequent; he avoids me and is extraordinarily nervous when he sees me. Apparently, he is well known and several neighbors and 1 merchant asked specifically if he had "cruised" by my house alot. I never mentioned his name. And he did "cruise" many times prior to the mower being stolen. Most all his "jobs" are out of town

Done what I can - out of options?
