The father of a black woman fatally shot in her home by a white cop in Fort Worth, Texas, has died after suffering a heart attack, according to reports.

The officer was charged with murder in the Oct. 12 shooting death of 28-year-old Atatiana Jefferson -- a case that has drawn national attention.

A family spokesman said her father, Marquis Jefferson, died Saturday at a Dallas hospital, Fox 4 Dallas reported. He had been hospitalized the night before.

The Dallas Morning News reported that Jefferson was 58 and that the cause of death was a heart attack.
