A federal jury in North Dakota will soon be deciding the fate of a man accused in a Jamaican lottery scam that authorities say cost victims around the country millions of dollars.

Attorneys are giving closing arguments in U.S. District Court in Bismarck in the case of 25-year-old Sanjay Williams, of Montego Bay, Jamaica, after about a week of testimony. He's charged with conspiracy, wire fraud and money laundering.

Authorities say the scam bilked mostly elderly and vulnerable citizens out of their savings.

Assistant U.S. Attorney Clare Hochhalter said in his closing argument to jurors that investigators reviewed more than 500,000 documents in the Williams case, including 50,000 emails from the defendant.

The case will go the jury after defense attorney Charlie Stock gives his closing argument.
