An Indiana teenager was found dead in jail days after being taken into custody for drug possession — and her family wants answers.

Shellby L. Hall, 18, was being held in the Madison County Jail at the time of her death, Indiana State Police said in a press release. She was reportedly arrested for possession of methamphetamines and driving under the influence. Investigators started looking into her death on Saturday, Nov. 11, when her body was discovered.

“The investigation by the detective indicated that sometime this morning, an 18 year old female inmate, identified as Shellby L. Hall, was discovered unresposive by correctional staff,” the press release said. “Jail staff and responding medical personnel provided medical care to the individual, however, she was pronounced deceased.”
