HILLSBORO, N.H. (AP) – A 76-year-old woman died Tuesday after catching fire while smoking and using an oxygen tank.

Neighbors said Barbara Brouillette was on fire when she ran into her backyard Tuesday morning. Fire officials said she caught on fire because she was smoking a cigarette while breathing oxygen from a portable tank. Her death was ruled an accident.

“Anybody on oxygen is not supposed to smoke,” said John Raymond, assistant director of the fire marshal’s office.

Neighbor Christine Silfvenius said Brouillette, a widow, suffered from heart problems and recently was diagnosed with lung cancer.

“She said, I smoked all my life,”‘ Silfvenius said. “She said, I had no regrets. I’ve done everything I wanted to do.”‘
