Brailynn's maternal grandfather says Anthony Ford claimed he had taken her for a ride, brought her home and put her down when he saw blood coming from her nose.
He says Ford even cast suspicion over whether the injuries came while the baby was in the care of his grandmother.
The family will hold a vigil at 7pm tonight in the 1000-block of Mosher Street, and Brailynn's funeral will be held at March Funeral Home on Wabash Avenue this Saturday at 10:00am.
The 21-year-old father of a Baltimore 5-month-old is in custody in the infant's death, Baltimore Police said.
Anthony Ford was arrested Thursday. He was charged with second-degree murder, child abuse resulting in death, first- and second-degree child abuse, and first and second-degree assault.
"I have trusted him with my kids. That's what hurts just as much. I have let him be around my 14-year-old, my two boys and I have another daughter that's nine and he watched his own child," explained Damon Wilson, the grandfather of baby Brailynn.
Due to signs of trauma, the death of 5-month-old Brailynn Ford was ruled a homicide.
"I couldn't even go in the room and look at her, but the pictures I saw of her---the first indication to me was somebody hurt this child," said Wilson.
"I'm going to make sure my baby gets justice if it's the last thing I do. I'm going to make sure whoever put their hands on her, they never put their hands on nobody else," added Davetta Parker, Brailynn's great-grandmother.
Officers were called to an area hospital for a report of the injured infant at 3 p.m. on Oct. 4. Police found the baby girl with signs of trauma being cared for by doctors. She succumbed to her injuries and was pronounced dead on Oct. 7. Her body was taken to the Medical Examiner's office, where the homicide ruling was made.
