A Riverview father is behind bars facing one count of aggravated child abuse.



Hillsborough County Sheriff’s investigators say Mitchell Stevens, 23, was taking care of his 4-month-old daughter, Marrie, on Wednesday afternoon when they say he picked her up and threw her several feet on to a bed.



That left her, investigators said, with bruised eyes and bleeding on the brain.



The child had to be taken to Tampa General Hospital where at last check she was listed in stable condition.



The infant’s mother, Izzie, said this is a big misunderstanding.



"But I want the truth to be found out,” Izzie said. “I want…if they can, do a lie detector test on my boyfriend so he can get out of jail."



The infant's mother is standing behind her boyfriend.



She believes it was her mother, who also lives in the house, who accidentally caused the injuries.



She said her mother fell with the infant in her arms.



That’s not true, according to investigators who say Stevens admitted to them that he got angry with Marrie because she wouldn’t stop crying.



Detectives said that Stevens told them that he made a mistake and because of it wanted to kill himself.



"I believe he loves his children more than anything and he would never hurt them,” said Izzie. “I don't believe he would do anything like this."



Neighbors say they just hope the baby survives.



"Like I can't even imagine,” said Martie Van Valkenburg, who lives next door. “There's no way I'd even put myself in that position. I mean, how could? It's a four or five-month-old baby."



'They need care,” said Dan Van Valkenbury, referring to the infant and her 2-year-old brother. “They need all sorts of care. They need a mom and a dad."



While, mom who is expecting another child, says she is hopeful that she can get her family back together again.



Fighting back the tears, Izzie said, "I want my boyfriend out of jail and I want my kids back at home with me."



Meantime, Stevens who is the biological father of all three children is locked up without bond.



The 2-year-old is in DCF custody.
