The Saline County Prosecutor’s Office has upgraded the charges against a Sedalia woman. Lydia Iliff, 32, was charged Wednesday with murder and endangering the welfare of a child in connection to the death of her 18-month-old daughter. A preliminary autopsy report cited “extreme dehydration” and “heat exposure” as the causes of a death. According to court documents, Iliff allegedly took off with her daughter in a stolen pick-up truck in July. A few days later she arrived at the home of a family member, disoriented and without her baby. The toddler was found on the bank of the Blackwater River the following day. Iliff was initially charged with one felony count of tampering with a motor vehicle. Her bond has now been set at $150,000.
