Jefferson’s father, Marquis has passed away from what is being reported as a heart attack. A spokesman confirmed the passing to the Dallas Morning News. Marquis Jefferson died Saturday at a Dallas area hospital.

“[He] just couldn’t get back from what happened to his daughter,” Bruce Carter said.

Last month, Atatiana, 28, was shot and killed after police went to her home for a welfare check. The officer who shot and killed Jefferson, Aaron Dean, was charged with murder.

Marquis Jefferson sought a temporary restraining order to gain control over the funeral arrangements for his daughter from her aunt.
