An Atlanta man was sentenced Thursday to more than six years in federal prison for his part in obtaining more than $1.6 million by filing false income tax returns based on stolen identities, authorities said.

Kelcey Pierre Miller “led a conspiracy stealing more than $1.6 million by filing fictional income tax returns that claimed enormous refunds using fraudulently obtained personal information of individuals in homeless shelters and jails. He not only victimized the taxpayers, but also preyed on the unsophisticated,” United States Attorney Sally Quillian Yates said.

Miller, 36, pleaded guilty to the charges on April 20. He has been ordered to pay restitution in the amount of $1,660,152, which is the amount of money officials say was fraudulently received from the government.

Miller and four co-conspirators filed 123 tax returns between December 2005 and March 2007 using information obtained from people in homeless shelters, jails and other places, then inflated their refund claims, according to authorities and court records.

Three of the co-defendants -- Rahman Hill, 40, of Mableton; Keith Lamone Richard, 40, of Decatur; and Peter Raymond Williams, 42, of Passaic, N.J. -- pleaded guilty to conspiracy May 23 and are scheduled to be sentenced later this month, authorities said. The other co-defendant -- Jabbar Ivan Pender, 40, of Newark -- is in federal custody in New Jersey on other charges.

Miller also pleaded guilty to aggravated identity theft for having a fake Georgia driver’s license with his photo but another person's information.

He was sentenced to six years and three months in prison, plus three years of supervised release.
