TULSA - Mark Grace was still in the prime of his life.
He was just 46 years old and known for his kindness.
"He was very innocent in so many ways," said Mark's niece Melinda. "Always willing to help a friend, a neighbor, your family. Everything."
But on a June night in 2008, someone stabbed Mark Grace to death.

"Anguish," said Melinda while crying. "No words can describe it."
Five years later, the pain for Mark's family is still almost too much to bear.
It's made even worse knowing his killer is still still on the loose.
"We know there's got to be someone who saw it and knows what happened," said Melinda.
Police who investigated the case believe late on that June night, Mark tried to break up a fight not far from his home near 67th & Utica.
Instead, he ended up dead.
"It was just an incident that he walked into that he wasn't a part of," said Melinda.
If anyone saw exactly what happened that night, they've never reported it to police.
"At this point what we're really needing is just that extra piece of evidence or witness, for somebody to come forward," said Jill Roberson of the Tulsa Police Department.
Police initially made an arrest in the case but later released the man due to lack of evidence.
"Anyone who did this in cold blood to a total stranger, can do it again," said Melinda.
Whoever did it, Mark's family wants them arrested and found guilty, for taking away their innocent mark.
