In a case officials said is exceedingly rare, a Houston woman charged with scamming a regional air quality program has been found living in Spring under an assumed name.

Shonda Renee Stubblefield, who also goes by Shonda McGowan, was arrested May 23 by U.S. Marshals and agents from the U.S. Department of Transportation Office of Inspector General, with help from Montgomery County deputies.

She was indicted in February in federal court, accused of theft of public money, mail fraud, wire fraud, money laundering, and aggravated identity. All of the charges stem from what officials called a scheme to defraud an air quality program administered by Houston-Galveston Area Council that spends federal funds.

The program offers grants and payments to help companies develop programs to reduce commuting, such as paying for technology upgrades to allow employees to work from home.

Stublefield’s company, World Corporation – which provided business consulting services – received $183,000 from the air quality program between August 2012 and April 2014, said Rick Guerro, a spokesman for the area council. The money was supposed to support a work-from-home program.

Federal officials later concluded Stubblefield had falsified paperwork and reimbursements for $125,659 over a two-year period to expand programs that did not exist. Along the way, authorities said, she fabricated items ranging from employee time sheets to bank records and fictitious lists of clients.

Fraud of federal air quality programs is rare nationally, according to federal transportation officials. In Houston, Stubblefield’s indictment is the only known incident since the air quality program began in 1991, according to the area council and a review of Chronicle archives.
