Dandridge said Mosley became upset and threatened to harm the child when he asked for custody. He said Mosley was angry at him and sent him the videos threatening to kill the child in retaliation.
He posted it on social media and it went viral. Dandridge, who lives out of state, said he posted it for one reason only.
"I just needed some help and I didn't know how to locate her," he explained.
He says a friend of Mosley's saw his post and told him where she lives, and that's how police found her.
Officers said the infant was taken to the hospital and was released.
Dandridge told Jones no father should have to see his child's life threatened like that.
"I guess she just went off the deep end. I don't understand," he said.
Dandridge said Mosley was angry with him over money and the fact that he wanted custody of his child.
Police said when they arrived at her home she had the baby and two other children, 5 and 7-years-old.
All the children are in the custody of child protective services.
