GRAND PRAIRIE (CBSDFW.COM) – Nancy Harris remains in critical condition after a man doused her with a flammable liquid then set her on fire during a robbery early Sunday morning.

Harris, 76, is well known in the neighborhood as the sweet convenience store clerk and die-hard Cowboys fan who greeted everybody with a smile.

Customers stopped in to the Whip In FINA gas station throughout the day to check on Harris’ status with the stores manager.

Harris had worked at the store for 14 years.

“Oh, she loved being around people. Ask every customer that would walk through that door they would mention Nancy,” said Harris neighbor and long time friend Jim Bertucci.

Concerned customers asked the store’s manager how they could help. They set up a donation fund to help pay Harris’ medical expenses.

“I thought well maybe I should stop by and leave a little something for her because she was just a nice lady and it was very shocking, disappointing,” said Antonio Gonzalez, who was a regular customer.

Meanwhile, the man accused in the crime, Matthew Lee Johnson, 36, remains in jail under a $500,000 bond, charged with attempted capital murder.

Harris’ family declined any interviews but asked for prayers.
