The shooting happened around 11:50 a.m. in the 1400 block of Springshire Court near Sunnybrook Road.
His family told ABC11 that the boy had succumbed to his injuries.
Raleigh Police said late Friday night that a juvenile suspect was in custody.
The boy's heartbroken father told ABC11 that the victim was his only child.
A neighbor told ABC11 he was in disbelief.
"It was so shocking," Ozzie Abrams said. "Cayden got shot, and I said, oh.
"At his own house ... at his own house," Abrams continued.
Their neighborhood on a cul-de-sac became the backdrop of an hours-long Raleigh Police investigation.
"It was so devastating," Abrams. "That is a nice kid. It was only a couple days ago he came by and said Ozzie, you got some snacks?"
Community advocate Diana Powell said, "When I get the call, and I hear the cries on the other end of the phone, it breaks my heart."
She got that call again Friday night.
"It's easy to go in your house, close your blinds, your doors, and say, that's not my problem until it becomes your problem," Powell said. "It is our problem."
Powell said she's seen more children dying, and the suspects have also been children. She said young people need more resources in the community.

"Resources are there, right?" Powell said. "They're just not getting to where they need to get to for it to be effective, right? We have resources. There is funding there, but it's not getting to where it needs to get to."
Meanwhile, Cayden's family and friends are processing an unimaginable loss.
"Too soon," Abrams said.
