'I found my daughter laid face down,' her father told WSB-TV. 'It was hard. I knew it was something wrong – her lips, her bleeding nose. They murdered my baby.'

He continued:  'They took everything from her, they took everything from me, and to see your daughter laid down, it's hard. There are no words for that.'

An autopsy as revealed her death has been ruled as a homicide. 

Police interviewed Jesus Monroy, the father of the unborn baby boy, on Wednesday. He was arrested for lying to police officers, but have not called him a suspect.

Campos's father believes the truth will come out soon. 'Justice is coming,' he said.

Miriam Zárate, Campos's mother, set up a GoFundMe for her daughter's funeral services.

'Mia, my daughter, the girl of my eyes, my baby, has passed away with her son in her belly,' her mother wrote. 'I ask God to watch over her and her baby, now she and my grandson are in heaven with God. With all my heart.'

Police said they are not releasing details surrounding Campos' death just yet. 

'So it's not just the loss of a victim but of her unborn child,' Sg. Collin Flynn said at a press conference. 

'The police department is taking this matter extremely seriously, as it should, so that's why we are withholding some information now.'
