Last week, police arrested 40-year-old Hayward resident Mishel Caviness-Williams, finding 900 blank credit cards, card printers, stacks of blank checks, and the personal information of thousands of people in her one bedroom apartment.

“We think we’re going to have a lot more victims than what we have, and I think the loss is going to be dramatic,” said Oakland Police Chief Anthony Batts on Monday.

“You don’t find labs like this making this amount of material to be falsified anywhere in the Bay Area.” Police suspect Caviness-Williams did not act alone.

Alameda prosecutors have charged Caviness-Williams with forgery, identity theft and grand theft. Caviness-Williams has a previous felony conviction for welfare fraud.

Police got help from the US Secret Service in their investigation, which started five months ago, after a City of Oakland employee reported someone was using her bank account to cash bad checks.
