Other Domino's restaurants participated and also donated the night's proceeds to Crimestoppers.
Joan Poythress and her son made a special trip to the pizza restaurant to help.
"[We] wanted to come out and support this cause 'cause it's very important that we find who was the cause of this," Poythress told ABC11 Eyewitness News.
She and other supporters came out to the Knightdale location where the robbery took place.
Twenty-four-year-old Ring died last month -- two days after a delivery driver found him on the floor of the Domino's -- injured from blunt force trauma.
"Kenny was good person," Micha Marshall, one of Ring's coworker said. "He never did anything intentionally to hurt anybody. It's just a shame that it had to happen to him?or to anybody as a matter of fact."
Ten percent of Domino's profits from Thursday night, earned between 4 and 10 p.m., will help bolster the $17,000 Crimestoppers reward.
"There's quite a few restaurants that are supporting this same cause tonight," Poythress said.
A sandwich shop next door to the Domino's where Ring worked and at least six other restaurants participated.
"I know we have made some progress, but hopefully the event tonight will help somebody come out and maybe remember something and get up with the police," Knightdale Mayor Russell Killen said.
According to Killen, police haven't said much in order to protect their investigation. The Eatern Wake News reported that police met with the Wake County district attorney Wednesday to review evidence and that police had two suspects.
Knightdale Police Chief Shawn Brown did not return ABC11's phone calls. However, residents are answering the call to bring peace to their town shaken by its first murder.
"It doesn't feel the same without him being gone, but we at least know people are making a conscious effort in trying to get whoever did this," Marshall said.
Even though there are reports that police have two suspects, Crimestoppers is urging anyone with information about Ring's death to call them.
