Police arrested one suspect in connection with the shooting of a Kannapolis teen.

Police took Damarick Harper into custody on charges of robbery with a dangerous weapon.

Officers are still searching for Darius Smotherson and a third, unnamed suspect.

As police continue to search for suspects, the family of Daniel Cooper, the teenager killed in the crime, spoke to Eyewitness News.

"The times we had with him, we're going to cherish," said Paul Ulm, Cooper's step-father.

Police say Cooper was in a car with a friend on Snow Street last Monday, when they were approached by three men who were apparently trying to rob them. At some point, a shot was fired and it hit Cooper in the neck.

"It happened when we were away and the police were here waiting for us," said Ulm. "It was just very surreal."

Cooper was just four days shy of his 18th birthday and three weeks away from graduation at A.L. Brown High School.

His friends there have painted a rock in his honor and written messages, which his parents have seen.

"He had a positive impact on a lot of his friends," Ulm said. "They would write things like 'just seeing you today and your smile, lifted me up.' "

Ulm said he primarily spoke on camera because he hoped someone would hear the story and reach out to Kannapolis Police with information that might lead to an arrest.

"You need to stop and think about what his senseless act has done to a loving caring family," Ulm said.
