Evans died April 5 in Austin days after he was punched and fell to the ground. When Evans fell, his head hit the pavement and he never regained consciousness.
Evans' mother, Missy, fought to have the Medical Examiner's office maintain her son's body until she could get a court order to have his sperm collected. In April, Missy Evans said said her son's dream was to some day have three sons of his own -- he had even chosen their names: Hunter, Tod and Van.
"Hunter was after Hunter S. Thompson, which was his favorite," she said. She started the legal process of having his sperm collected so that his dream could be fulfilled and his legacy would live on.
The arrest Friday of Eric Skeeter is bittersweet for the Evans family.
"Its just a mixture of like, happiness and sadness you know," said Nikolas' brother, Ryan Evans. "Happy that they got somebody and sad because it brings back the memories of losing him."
Ryan Evans spent several days after the incident handing out fliers in Downtown Austin, trying to get information about the crime. It was so random, says Evans, he was not sure if anyone would ever be arrested.
"It was just random, that's why I never thought it would get solved , but they got him," said Evans.
Police would not say how they tracked Skeeter down in this case. He has a $150,000 bond.
