Court documents, obtained by 11 News, spell new details in the death of a 4-year-old girl. Extensive internal injuries claimed her life. Her mother's boyfriend is charged with the murder. Now that mother wants answers.

Tamyrill Randall had eight broken ribs and a liver torn in two, according to the El Paso County Coroner’s Office. She was murdered over the weekend in Security.

The suspect's brother and the little girl's mother spoke with 11 News. They say they had no idea Tristan Price was locked up for murder. They thought he was arrested for domestic violence.

"I just want to figure out what happened to my daughter," said Tanesa Randall, Tamyrill’s mother.

"I don't have any answers. Other people know more about the results of my daughter's autopsy than me."

According to court documents, Tamyrill died from some kind of severe trauma. The coroner has even suggested the injuries could have happened when someone stomped on the child. The documents said that could cause the 4-year-old's ribs to crack and her liver to split open. She also had a bite mark on her shoulder blade.

El Paso County Sheriff detectives said the suspect, Tristan Price, was supposed to be taking care of her. He told cops he found Tamyrill was unresponsive and tried to revive her in the shower. Then, he called 9-1-1.

Price's brother, Michael, said Tristan would have no reason to harm the girl. "I want to get to the bottom of it regardless of the evidence. At least, if it’s presented and shows that he did do this, I will be fine and able to get closure," said Michael.

Also according to the documents, the sheriff's office noted they found records that Tristan Price had been investigated in the past for abusing the same little girl when two bite marks were apparently found her chest. No charges were ever filed. In that same arrest affidavit, Tanesa Randall admitted to cops that her boyfriend would bite her when he's angry.

"I want justice as well. Whoever did this, I want them to pay for the consequences," said Tanesa.
