Tenants skipped--tracking them down

[John Knappmann]

I had a SFR in Michigan that I rented to two guys in their early twenties. Paid first month in advance, could not contact them when month two came up. I filed for eviction, but still need to track them down to get the money they still owe. They might be living with their parents again.

Any suggestions on resources I could use to find them? It's not worth spending too much money searching for them, but I want to make an effort. Small claims court so litigation costs will be minimal.
