Atatiana Jefferson was shot and killed last month by now-former Fort Worth police officer Aaron Dean during what was supposed to be a welfare check.
She had been playing video games with her 8-year-old nephew in her home in the early morning hours of October 12 before being fatally shot by Fort Worth police officer Aaron Dean through her bedroom window.
"Please keep his family in your prayers and tonight make sure you hug and tell your loved ones how much you love them", Carter said.
Carter told KDFW-TV that Marquis Jefferson had been battling chronic obstructive pulmonary disease (COPD), an inflammatory lung condition that obstructs airflow and makes breathing more hard.
"He ultimately just succumbed to, I don't know, I can only say a broken heart", Carter told CNN.More news: How 'Crazy Rich Asians' paved the way for 'Last Christmas'

Instead of announcing himself at the front door, Dean crept around the back of the home, gun drawn and unannounced, according to his arrest warrant and bodycam video.
Following the shooting, Marquis filed a restraining order to delay his daughter's funeral due to a family dispute.
"And that smile? Lord have mercy", Marquis Jefferson said last month in memory of his daughter.
After the shooting, Ed Kraus, interim chief of the Fort Worth Police Department, characterized Jefferson grabbing her licensed handgun as reasonable self-defense and vowed accountability for the officer who shot her. He was granted the release and was able to take full control of his daughter's arrangements.
Democratic candidate for President Julián Castro tweeted that Marquis Jefferson's death "is a reminder that the victims of police violence also include the families of those killed".
He said that as his daughter's sole legal heir, the duty of arranging the funeral is his. Her service took place October 24 after a judge issued a temporary restraining order in her father's favor.
