FILE - In this Aug. 24, 2010 file photo, R. Allen Stanford arrives in custody at the federal courthouse for a hearing in Houston. On Tuesday, Jan. 24, 2012, after much delay, federal prosecutors in Houston are due to begin laying out their case against Stanford, telling jurors that the 61-year-old’s business empire was built on smoke and mirrors and that he bilked investors out of more than $7 billion over 20 years as part of a massive Ponzi scheme.

HOUSTON — One of Texas financier R. Allen Stanford's former employees tells jurors he believes he saw Stanford make up accounting figures used in an annual report to woo investors.

Leo Mejia ran an advertising agency owned by Stanford. Mejia testified Wednesday at the financier's fraud trial in Houston.

Mejia said he saw Stanford and his chief financial officer make various faulty changes to figures related to the bank's finances just before they were approved for an annual report for Stanford's bank.

Federal prosecutors contend Stanford used money investors deposited in his Caribbean bank to fund his businesses and lavish billionaire lifestyle.

Stanford's attorneys say his businesses were legitimate.

Stanford is charged with 14 counts, including mail and wire fraud. He could face up to 20 years if convicted.
