LOUISVILLE, Ky. (WDRB) – Savannah Sparks was a daily heroin user. LaKenya Porter had congestive heart disease and could not even stand. Samantha George had severe diabetes.

All of these women entered Louisville Metro Corrections in 2012, and all died while in the custody of the jail.

But despite their medical problems, two of the women's deaths could have been prevented and the lack of care while in jail contributed to the death of the third woman, according to recently concluded investigations by the Louisville Metro Police's Public Integrity Unit.

In reviewing the investigations, the Jefferson Commonwealth's Attorney's office found no criminal conduct but criticized Metro Corrections as well as Corizon, the private company that provided the jail's medical care at the time.

The investigations, which were completed late last month, include dozens of interviews with medical staff, jail officers, reviews by a forensic medical examiner and conclusions by the Commonwealth's Attorney's office. WDRB obtained the records through an open records request of Louisville Metro Police.
