The lawyer for a man on trial in North Dakota in a Jamaican lottery scam case says authorities should have investigated whether his client was himself a victim of stolen identity.

Twenty-five-year-old Sanjay Williams, of Montego Bay, Jamaica, has pleaded not guilty in federal court to conspiracy, wire fraud and money laundering. He's the first of 32 defendants to go to trial.

While questioning FBI Special Agent Frank Gasper on Wednesday, defense attorney Charlie Stock said investigators should have looked into an incident in which Williams' email account was hacked. Stock said they should have checked whether Williams' credit card information was stolen.

Gasper said there's plenty of other evidence against Williams.

Stock said so many people in the case used fake names that it's hard to believe any witnesses.
