A Cobb County husband and wife were convicted Friday of stealing $1.3 million from the woman’s employer, the county’s District Attorney said.

A jury convicted Angela Lynn Williamson, 45, of Marietta, on three counts of Violation of Georgia Racketeer Influenced and Corrupt Organizations Act, or RICO, DA Vic Reynolds’ office said. Scott Brian Williamson, 47, was convicted on two counts of RICO.

“She stole it and he helped spend it,” Deputy Chief ADA John Melvin told jurors. “Together the two averaged $80,000 per year in legitimate income, yet they bought three homes, two boats, four cars and had a personal chef. They enjoyed a lifestyle they could not afford but for the thefts.”

Angela Williamson began working for InterContinental Marble, a Marietta-based importer of stone for fireplaces, Reynolds said in an emailed statement. She was the officer manager and handled booking and accounting duties, but also changed passwords on company bank accounts without telling her employee.

The company’s CEO, Karen Geiger, testified that she discovered there was a problem in May 2011, when she opened the mail while Angela Williamson was out of town.

In May 2012, The Atlanta Journal-Constitution reported that Angela Williamson was arrested and charged with 11 felony counts of theft by taking. At that time, she was accused of stealing nearly $1 million from the company.

In 2002, the alleged thefts totaled $14,315.50 from five checks Williamson allegedly issued to herself, her arrest warrant states. In 2007, Williamson allegedly issued herself 57 checks totaling $147,090.93, according to police.

Angela Williamson pleaded guilty in 1999 to stealing $135,000 from a previous employer, Cardiovascular Medicine, Reynolds said. She was granted First Offender treatment in that case.

Scott Williamson was booked into the Cobb County jail after his conviction Friday. His wife has been in jail since being re-arrested in May 2013, jail records show.

Sentencing for the pair is scheduled for May 20. Each of the Williamsons face a maximum of 40 years in prison and a fine of three times the amount of the theft, Reynolds said.
