A spokesman for Marquis Jefferson, Bruce Carter, tells the Dallas Morning News that the father of Atatiana Jefferson suffered a heart attack and died Saturday night at a Dallas hospital. Carter tells KDFW that Jefferson "just couldn't get back from what happened with his daughter."
The 28-year-old Jefferson was killed last month after police went to her home for a welfare check. The Fort Worth officer, Aaron Dean, was charged with murder after resigning from the force.

After his daughter's death, Marquis Jefferson sought a temporary restraining order to gain control over the funeral arrangements from his daughter's aunt. A deal was eventually reached and the funeral was rescheduled.
