(Knox, IN) - Charges have been upgraded in the death of a baby in Starke County. Justin Miller is now charged with murder.

Authorities say he was babysitting for the parents of 11-month old Mercedes Lain more than two weeks ago. Miller allegedly told investigators he was sleeping and woke up to find the baby girl dead.

Miller later led prosecutors to her body off a country road. Initially, he was charged with the neglect of a dependent, causing death. The murder charge, which calls for more prison time, was filed yesterday. The parents are charged with child neglect.

So far, the cause of death and other details have not been released.
