After kissing her two children for the last time, Kametra Sampson told stories about them and shared how much they meant to her with attendees.

“Naim was my oldest, he was five,” she said, “He was just a friend I never had. They were happy. They were happy kids.”

Police suspect the boys’ father, Naim Rasool Muhammad, 32, kidnapped the children and drowned them last week. He faces two capital murder charges after confessing to the crime, police said.

Many came forward Saturday simply to offer encouragement. Five-year-old Naim was supposed to start kindergarten at Julia C. Frazier Elementary on the day he was killed. The principal of his school attended the funeral to show her support.

“Please know we will continue to keep you in our thoughts and prayers,” said Rachel George.

Neighbor Arnetrus Green remembered one of the happy moments with the boys. She spoke of the time they helped her with her garden.

“They stepped on more seeds than they planted,” Green said. “But I was proud that they were that young and came over to try and help.”

As the two families worked to heal from the loss, they made a vow that Naim and Elijah would not be forgotten.

“I’m going through a lot right now, but I’m beginning to accept the fact that my sons are in Heaven,” Sampson said.
