Nate Cumberland died of severe head injuries but how he received those injuries is still a mystery. His friends are asking for help.
On Sunday afternoon they were busy again spreading the word in the area of 24th and Harney where Nate lived.
Zach Beiermann, a friend of Nate's for ten years, told Channel 6 News, "We know this is not the best area of town, there's gotta be somebody that knows something, somewhere."
Cumberland was severely injured sometime between 5pm on February 27, 2013 and 5am the next day.
He died in the hospital after spending a week in a coma.
Another friend, Melanie Schuler said, "He had three traumatic hemorrhages on the brain and his brain actually shifted in his skull."
She was referring to the results of an autopsy that the family shared with her.
The results of the autopsy did not give Omaha Police a definite cause of the injuries. Police tell Channel 6 that the investigation remains open.
Cumberland's friends believe it was an act of violence and that somebody knows what happened.
"They're not just gonna beat somebody and leave em in the alley and never talk about it again," said Beiermann. "That's not what people that do that kind of thing do, they're gonna brag about it."
Melanie Schuler added, "It doesn't seem like somebody could just accidentally fall down and have your brain shift and gotten that many different injuries on your skull like that, the not knowing is really hard."

Cumberland's friends have organized a benefit concert to raise money for a reward fund.
It will take place April 27th at The Pizza Shop, 6056 Maple from 7pm to midnight. A $10 minimum donation will be collected at the door.
