LOUISVILLE, Ky . (WDRB) -- Two years after 26-year-old Nick Hart was killed, his family said they have even more questions.

Hart's family said he was killed in a vicious attack, however the Commonwealth’s Attorney’s Office said it was a case of self-defense.

“Life will never be the same without him, especially to us or our family,” said Faith Darland, Hart’s sister.

On July 9, 2016 Hart was in a fight on Taylor Boulevard not far from Iroquois High School. He ended up with a severe brain injury.

“Somebody picked him up and slammed him down against the concrete and cracked his skull,” Darland said.

Doctors removed a piece of his skull to relieve pressure, but it wasn't enough.

“At the end of the day, there was just too much brain damage, and we had to do what was best for him,” Darland said.

While what was best for him was to let him go, it was the hardest for his family. On July 26, 2016, Hart died. His family said to add insult to injury, the commonwealth’s attorney ruled his homicide as self-defense.

“It's just hard for me to believe that this is self-defense. Two against one,” Darland said. “And just to leave a 26-year-old on the side of the street and say it's self-defense, it's very hard for me to believe.”

Darland just wants answers as to how this decision came to be, but she said the family can't see to get any.

“I have wrote letters to the mayor, I have wrote to the commonwealth of Kentucky, everything,” she said. “Can somebody explain to me ... just open me up to know how this is self-defense?”

Until then, Darland said family and friends will keep his memory alive.
