A key prosecution witness in the Bell corruption case testified Wednesday that signatures on city contracts, minutes for council meetings, agendas and even resolutions were forged.

Bell City Clerk Rebecca Valdez's testimony could bolster the defense's argument that record-keeping in Bell was so sloppy that it would be difficult to prove that six former council members inflated their annual salaries to nearly $100,000 by serving on boards and commissions that met for a few minutes, if ever.

On her third day on the witness stand, Valdez said she noticed the forgeries in 2010 when pulling together records requested by investigators looking into possible wrongdoing. She said she never looked into the forgeries, and didn't make a list of the questionable documents.
