(CBS) –The mother and nephew of Ebola victim Thomas Eric Duncan have been brought to Chicago by the Reverend Jesse Jackson, who is advising them.

They are speaking out, and they are angry.

“He’s like my brother, my uncle, my best friend and to snatch all that from me, I’m a little upset,” Josephus Weeks said Saturday, following an appearance at Rainbow/PUSH.

Weeks and Duncan’s mother, Nowai Korkoyah, both said they do not believe Duncan was treated as a human, much less given the treatment afforded to the infected health care workers flown from Africa to Atlanta.

“If he did what (some say) he did in Africa by helping a pregnant woman, that’s humanity,” Weeks said. “He risked his life. That’s honorable to me.”

The 19-year-old woman died several weeks after Duncan may have helped her, although it is unclear if he actually did so.

“They did not treat him the way they are supposed to treat Ebola,” Korkoyah said in broken English during the Rainbow-PUSH meeting.

Both said they want answers from Presbyterian Hospital in Dallas and its owner, Texas Health. Rev. Jackson raises the possibility of a malpractice suit.

“It’s difficult to miss, if you follow the protocols,” Jackson said. “From West Africa, where the disease is running rampant. Signs include high fever. His temperature was 103, and he had been vomiting and perspiring.”
