Acting D.C. Attorney General Irvin B. Nathan, saying funds “may have been mishandled,” has referred the findings of a DCPS investigation into the use of a $100,000 award to McKinley Technology High School from AARP to the U.S. Attorney’s Office.

D.C. school officials have spent the last several months attempting to determine what happened to the 2008 award, intended to fund a community service program in which McKinley students would tutor senior citizens on how to use the Internet. But the program never got off the ground, and the DCPS security division has had an investigator looking at McKinley’s finances.

Nathan’s letter Tuesday to U.S. Attorney Ronald C. Machen Jr. did not elaborate on the school system’s findings. But he said: “Information developed during this investigation suggests that these funds may have been mishandled.”

William Miller, Machen’s spokesman, said he could not comment in detail on an active investigation but that the office “is conducting the appropriate review.” Neither Chancellor Kaya Henderson nor her spokeswoman, Safiya Simmons, responded Wednesday afternoon to e-mailed requests for comment.
