So was it the queen-size therapeutic mattress pad? The deodorant, laundry soap, body wash and feminine hygiene products? The leather jackets, purses and dozens of vases seized from her home? Whatever it was, we're glad something convinced a federal jury that Marsha Ollison of The Colony misused her DISD credit card on items that might not have had, shall we say, direct educational purposes. That jury found her guilty Wednesday of three counts of felony theft for about $56,000 in improper charges from 2003 to 2006. Ms. Ollison, 43, a secretary in the superintendent's office, could get 30 years in prison and is the first of what we hope will be a number of DISD employees paying a criminal price, at long last, for stealing from kids' futures.
