"Its just so hard. I just can't believe that my baby is gone," said Marilyn Powell through tears.
Thompson had no shoes or socks on. Her family said she was found also without a wallet or a phone.
"She went nowhere without her phone. I mean she slept with that phone, she ate with that phone, she did everything with that phone," said her father Robert Thompson.
Her dad said when he identified her body there were bruises on her. But the Winnebago County Coroner Bill Hintz could only say the death is suspicious. Her dad is not even sure how she ended up in South Beloit. He knew she had friends in Janesville but that is still 45 minutes away.
"She was staying with some friends down there and all of a sudden those friends disappeared, don't nobody know nothing now," said Robert Thompson.
Her family thinks someone left Thompson under that truck and they want to know why.
