Hill said police were looking into how two 16-year-old girls were able to rent an apartment on their own. He would not release the name of the building's management or the address, but Tye said the apartment was in Finley's name.
Tye said she's hoping that her granddaughter will be able to receive a psychiatric evaluation while in custody.
"I want Tatianna to get the help she needs," she said.
Hill said that while it was unusual to bust two teenage girls for running a prostitution ring, he couldn't say it was shocking.
"When you're dealing with child prostitution," he said, "there's really no surprises anymore."
