The brother of a woman who was fatally stabbed last month speaks to News 12 exclusively about his ongoing pursuit to seek justice. 

Gina Cooks was one of three stabbing victims who died on Aug. 25. 

Her brother, Devon Washington, says he was at home with his daughter when he got the call about his sister being stabbed. 

Washington says Cooks was one of his closest siblings since she moved to New York from Alabama and that she was very important to him. 

"I would always visit her at the parks, we would have the brother-sister talks," said Washington. "I was always hard on her because I wanted her to be the best." 

Washington started a GoFundMe account to help cover the funeral, which he says is on hold until he can pay for the arrangements. 

Cooks leaves behind an 8-year-old son and 3-year-old daughter. Washington says they're currently with a caretaker but he's going to do what he can to provide for them. 

"Amir and Adora deserve the world and I'm prepared to give that to them." Says Washington. 

Before she was killed, Washington says that Cooks was working on finishing her GED and was preparing to start a new job in Atlanta to further her nursing career. Roberto Jimenez, who Washington says was Cooks' fiancé, was one of the other victims killed in the stabbing. 

"It hurts, I'm mad, because she doesn't deserve this and the person that did it to her lived his life and took a young one, and she had so much potential," said Washington. 

Police arrested 55-year-old Derrick Williams in connection to the triple stabbing and he's facing two counts of murder and one count of attempted murder.
