In addition to murder, records show Kimrey was also charged with felony child abuse resulting in serious bodily injury/death.
The man was initially being held on several other charges including concealing an unattended death.
An autopsy conducted on December 4 provided a preliminary cause of death; however, additional chemical and toxicology tests were required.
The Medical Examiner's Office determined that chloroform - a liquid used as a general anesthetic - was determined to be the cause of Mariah's death.
