A dozen women and one man were indicted by a Prince George's County grand jury Wednesday on charges of welfare fraud, Medicaid fraud and perjury.

According to Assistant State's Attorney Edmund O'Connell, most of those were indicted as a result of cross-checking benefits paid by the Social Security Administration or Maryland's Department of Social Services that indicated they were unemployed.

For example, Andrea R. Woodby, 27, of Forestville, was apprehended when she filed a change of address, O'Connell said, and investigators discovered she was married and being supported by her husband.

She was charged in connection with $9,900 that prosecutors said was fraudulently obtained.

Also indicted and the total amount of benefits they are accused of fraudulently obtaining were:

Jeannette and James Davis, both 35, of Aquasco, $13,000; Pearl Grady, 47, of Glenarden, $4,900; Zelma Butler, 35, of Lanham, $1,600; Laverne Curtis, 27, of Brentwood, $6,800; Sonia Shand, 26, of Chillum, $3,700; Lanette Burkley, 24, formerly of Forestville and currently of Washington, $4,100.

Eva Rusk, 20, of New Carrollton, $2,000; Mary Louise Florence, 38, of Suitland, $6,500; Effie Morton, 37, of District Heights, $2,800.

Also Ruth McClain, 40, of Landover Hills, $6,700, and Crystal Hill, 21, of Brentwood, $6,500.

O'Connell said the penalty for welfare fraud is a maximum of three years in jail, and/or a $1,000 fine; the penalty for Medicaid fraud under $500 is the same, but for an amount higher than $500 the penalty is a maximum of 5 years in jail and/or a $10,000 fine.

The penalty for perjury is a maximum of 10 years in jail.
