A Marina del Rey man has been convicted of federal fraud charges for his role in a scheme where he and his brother impersonated victims to obtain and use credit cards in their names.

A federal jury on Friday found Johnny Stewart, 50, guilty of 18 felony counts, including conspiracy to commit bank fraud, bank fraud, access device fraud, aggravated identity theft and money laundering. The jury deliberated less than two hours following a four-day trial.

Evidence was presented showing that Stewart and his brother, Clayton Stewart, fraudulently applied online for unauthorized credit cards from institutions such as Chase Bank USA, Bank of America and Capital One Bank.

Losses associated with the scheme were estimated at about $600,000, authorities said.

Stewart faces a maximum sentence of 302 years in federal prison. Sentencing is set for March 18.

His brother, Clayton Stewart, 46, of Bellflower, pleaded guilty to conspiracy to commit bank fraud, access device fraud and money laundering and will be sentenced on Feb. 4.
