LOUISVILLE, Ky. (WDRB) -- Police are struggling to prove what happened inside the Clarksville home where a three-year-old girl died.

Medical reports say Alexis Arensman was horrifically abused, suffering broken ribs, head injuries and a burn on her face likely from her mouth being taped shut.

The three-year-old died nine months ago and just yesterday her mother and mother's boyfriend were charged. But Joseph Manske and Cynthia Weigleb are only accused of neglect. Prosecutors say they don't have enough evidence for a murder case.

"We don't stop just because the arrests are done," said Scott Merchant of the Clarksville Police Department. "And if any more leads come in, we'll turn those over to prosecutors to see if anything else can be changed on it."

If convicted, Manske and Weigleb face 56 years in prison.
