Carter told KDFW that Jefferson had been battling chronic obstructive pulmonary disease and was under a lot of stress in the few weeks since his daughter's death.

"He ultimately just succumbed to, I don't know, I can only say a broken heart," Carter said. "He just never recovered from the grieving process."

Atatiana Jefferson, 28, was Marquis Jefferson's only child.

She was killed on Oct. 12 while playing video games with her 8-year-old nephew. Fort Worth officer Aaron Dean, 34, fired fatally into her bedroom window while conducting a wellness check.

At a press conference last month, Fort Worth Police Lt. Brandon O'Neil said Dean never identified himself as police, sparking national outrage and claims of excessive policing. Body camera footage released by the Fort Worth Police Department also appears to confirm that Dean did not identify himself as police before he shot. Dean resigned before he could be fired in connection with the shooting. He was released on a $200,000 bond after he was arrested and charged with murder.

Marquis Jefferson made headlines in the weeks following his daughter's death as he sought a temporary restraining order to gain control over her funeral arrangements from his daughter's aunt. He said that he had been denied any involvement in the funeral planning and as his daughter's sole legal heir, it was his duty to arrange it. A deal was eventually reached, and the funeral service took place Oct. 24.

Sacramento Kings star Harrison Barnes and Philadelphia Eagles defensive tackle Malik Jackson helped cover the funeral costs for Atatiana, according to Jefferson family attorney Lee Meritt.
