CONCORD -- This Wednesday will mark four years since two innocent bystanders at the Concord Sundrop plant were shot and killed at random. Police said new information continues to emerge, but has yet to lead to a suspect.
Those still working at Sundrop said that they still have not given up hope.
"This is our family business so, you know, it's like it happened in my home. I take that very personally." said Sundrop President, John King. King said there isn't a day that goes by when he doesn't think about the two people killed at the Concord plant four years ago.
"It's been four years but it's still pretty fresh," King said.
Donna Barnhardt and Darrell Knowles were murdered at Sundrop on June 13, 2008.
Barnhardt had been an employee there for almost 20 years and Knowles was applying for a job when police said they were randomly shot and killed.
"Our employees don't go hardly anywhere where somebody doesn't mention something about it. Most of the time they just mention that we're still in their thoughts and prayers," said King.
Sundrop has upgraded security and procedures in the last four years, said King.
He also said that he keeps in contact with Concord Police, who said that this case is as much a priority now as it was in 2008.
"The same investigators working the case four years ago are the same ones working it now," said Concord Police Chief Guy Smith.
Chief Smith said that a sketch of the suspect has generated hundreds of tips across the state, even as recent as last week.
"There hasn't been anything that I'm aware of that's came in that hasn't been followed up on, looked at and ran out as far as we could run it." said Smith.
Still investigators aren't any closer to an arrest.
King hung fresh sketches Tuesday at the plant because he said he hasn't given up hope.
"No, I have not given up, we still, first of all, pray for the police safety, second of all pray for their success and, of course, that's after we pray for all the families involved." King said.
An $85,000 reward still stands for information leading to an arrest and conviction in this case.
