An 83-year-old Prince George’s County woman who had been a longtime state legislator and teacher died Saturday after being pulled from a fire at her home last week, authorities said.

Christine M. Jones died at a hospital in Baltimore after being found Thursday in her home in Temple Hills, said Mark E. Brady, spokesman for the county fire and rescue service.

The cause of death has not been determined by the office of the state medical examiner, Brady said. He said the blaze was still being investigated by the county fire marshal’s office.

Jones had a 30-year career as a teacher and educator in the county school system, where she specialized in physical education.

She represented Prince George’s in the state House of Delegates from 1982 to 1994. In 1994, she was the assistant floor leader for the House’s Democratic majority.

During a reelection campaign, she described diligent efforts on behalf of economic development, education and social progress.

She said in biographical information that she had been vice chairman of the county’s delegation and a former president of the state’s legislative black caucus. She had also been secretary of the women’s caucus, she said.

Jones was found in her one-story brick home on Everest Drive, where firefighters were called about 11 a.m., Brady said. She had no pulse and was not breathing, he said. The fire was thought to have started in a bedroom.
