A day after family members made an emotional plea for the community to help police solve a young father's killing at a popular late-night restaurant, police have made three arrests in the case.

Until recently, homicide detectives and family members said they were frustrated because they'd received so few tips, even though Devon Clement was shot in front of dozens of people at the Cook-Out restaurant on West Sugar Creek Road.

The May 16 homicide was the first of five killings in a five-day period.

Charlotte-Mecklenburg police Sgt. Lisa Mangum said Saturday that until recently, officers had received "just one or two" tips in Clement's case.

On Friday morning, Clement's mother, Desiree Clement, and his stepfather, Owen Chase, asked the community for help in solving the case, though Mangum said the arrests were based on evidence officers had obtained earlier.

Antonio Gerrick Hamilton, 19, turned himself in to police early Saturday morning, though it's unclear what made him show up at police headquarters. About 2:30 p.m., the department's violent criminal apprehension team arrested Shamon Monair Goins, 19. And about 5 p.m., police announced that 20-year-old Cherelle Monet Griffin had turned herself in.

All three are charged with murder and with shooting into an occupied building. They were in Mecklenburg jail Saturday evening, according to police, and will make a first appearance before a judge early this week.

Police say Clement was shot and killed during an argument in the Cook-Out parking lot about 4 a.m. May 16. Detectives said there had been gang activity in the area that night, but there was no indication that Clement was involved in gang activity or had done anything to provoke the shooting.

"He was a good young man, working to make the most of his life," his mother said Friday.
