'Severe pain in his final moments'

On the day of his death, Jelani's mother, Diasia Williams, dropped her son off at Johnson's home, WANF-TV reported, and said Johnson contacted her and said Jelani was unresponsive and that he had called police.

According to the Sandy Springs Police Department, officers responded to Johnson's apartment and first responders "rushed the child" to Children’s Healthcare of Atlanta where he was pronounced dead.

An autopsy revealed Jelani suffered blunt force trauma injuries, a broken femur and bleeding on the brain that resulted in his death during care by Johnson, according to police, who later arrested Johnson in connection to the baby's death.

“The child was severely abused and would’ve suffered severe pain in his final moments,” Robert Shapiro, a senior district attorney who prosecuted the case, told WANF-TV about the tragedy. “This was an especially difficult case, given the age of this victim. "

Remembering Jelani

Olythina Holt, who created an online fundraiser to help pay for the baby's memorial service, called Jelani "a happy little one and the center of his family.

Jelani made an impact on so many "in just the little time he was here with us," Holt posted on the fundraising page. She also went on to say, "He was able to brighten your day with his bright eyes and contagious smile. "
