Police said he was an innocent child caught in the crossfire.
It happened around 6 p.m. in the 14000 block of Highway 72 West in Red Springs.
Surveillance video shows Alva Oxendine's mom clinging to her son, banging on the door of the police department for help. Minutes later, police and EMS arrived. He was taken to the hospital but later died.
"This is an innocent baby that didn't deserve to die," Red Springs Chief of Police Ronnie Patterson told ABC11.
Although the case is being handled by the Robeson County Sheriff's Office, Patterson knew the family well.
"Yesterday I was little upset about a five year old passing away in a senseless killing," he said. "Today I feel like I'm a little angry about it and we want to send some closure to the family."
Police say it all started when two women agreed to meet up and fight. According to Patterson, the mom was only there to check on one of her family members who was involved. But that's when gunshots broke out.
One hit the 5-year-old boy who was strapped in the back seat.
"This is going on around the country and around the state. It's got to stop one way or the other," Patterson said. "We have to get a hold of gun control and educate folks but in the heat of the moment all that goes out of the window with folks and they don't think in the heat of the moment."
Peterson Elementary School, where Alva went to school, said there was extra support staff on campus Thursday.
"In times like this we must pull together and lean on one another," a Facebook post from the school said. "Continued prayers for AJ's family & friends..."
Patterson said the family was able to give a solid description of the shooter.
Anyone with information about the case is asked to contact the Robeson County Sheriff's Office at (910) 671-3170.
