Police say the boy's stepfather, 35-year-old Marcas Fisher, is a person of interest in the case.
Investigators say Dae'von was a victim of child abuse. His body was removed from his home by coroners shortly before 11 p.m. Thursday.
The LAPD was called to the home on the 800 block of East 87th Place at around 6:30 p.m. to investigate a possible death. When officers arrived they found the first grader dead with multiple unexplained injuries, including blunt force trauma.
Police say Fisher was the last known caretaker of the child, but he was gone from the home when paramedics and officers arrived.
The child's family says Fisher had called family members Thursday telling them he had beaten the young boy. Family members say the child didn't deserve this violent death.
"That's really hard for me to understand who he would go to that level, you know what I'm saying, knowing that that's a child," said Kiara Sharp, the victim's aunt. "If you felt that much anger you should have went around the block or something. You know, go get some air or something, you don't put your hand on no child like that."
Dae'von's mother, who has five other children, four of whom are in protective custody, says Fisher was caring for her young son while she found a place to live. She said she never thought her ex was capable of such violence.
"I was shocked, surprised. You know, I never thought he, you know, would do something like that to my son," said Tylette Davis, Dae'von's mother.
Family members insist the stepfather killed the boy and is now on the run. The boy's mom is urging Fisher to turn himself in.
"I just want him to turn himself in because what he did to my son was wrong and he took a big part of me, a part of my life," said Davis.
Neighbors say the family had only moved into the neighborhood a few months ago. They say they hadn't seen any signs of trouble.
"Every time I've seen them, they're, you know. a bunch of kids in the yard playing, happy, friendly, you know, normal kids," said Tasha, a neighbor.
Family members say the boy was an extremely quiet boy who loved to play outside. They say they can't believe he is gone.
Authorities are not calling Fisher a suspect, but they do want to talk with him.
