Complaint / review text:
Knew this guy must be up to something so I searched on Google; putting up this info in case it might help somebody, even though it's old.
Derek Fermin moved from Wichita to the San Francisco area in 2000 and apparently moved back to Wichita in 2001. While in California he definitely:
* Counterfeited many $20 bills, in collaboration with a Russian national, a minor by the first name of Yuriy, who lived in Marin County, Calif.
* Created checks for phony checking accounts. He left evidence behind. I witnessed him trying to pass these checks (which at the time I didn't know were fraudulent) at a Wal-Mart in San Leandro and at California Check Cashing in Oakland.
* Bought items using phony checks, returned items for store credit, purchased more items using store credit, and then returned them and received cash. I witnessed him do this at Wal-Mart in San Leandro, Calif.
Apparently he is very familiar with return policies at various stores.
Easy name to remember: rhymes with "vermin."
