The Jefferson County Sheriff's Office is investigating the Friday afternoon death of a 3-month-old girl, and the child's parents have been arrested on unrelated charges, according to a JCSO news release.

The news release said that the girl's body was found inside a Jefferson County home or a vehicle parked at a county residence but wasn't specific as to which scenario took place.

The news release said that deputies responded to a 911 call at 1321 Lindsey Dr. Friday related to the report of an infant who was unresponsive.

Deputies and investigators, along with paramedics from the Emergency Ambulance Services, Incorporated, arrived at the home a short time later and discovered the lifeless body of a 3-month-old infant girl, the news release said; however, lifesaving efforts were unsuccessful.

Jefferson County Deputy Coroner Eric Belcher was called to the residence, where he pronounced the death of the infant at 12:27 p.m., the news release said. The infant’s body will be sent to the Arkansas Medical Examiner’s Office for an autopsy in order to determine cause and manner of death.

“Investigators executed a search warrant at the residence in search of evidence that would aid in their investigation. Meanwhile, other investigators conducted interviews of family to try to find out how the infant died," said Jefferson County Sheriff’s Office Operations Commander Major Randy Dolphin.

"This is a tragic event that happened and affects everybody in the community."

Dolphin said the 3-month-old did not have any obvious signs of trauma but that investigators were treating the call as a death investigation and will await the preliminary autopsy findings and results of the medical investigator to determine the cause of death.

The infant’s parents, 38-year-old Nicholas William Crist, and 33-year-old Brandi Lynn Crist, were on scene, according to the news release.

Nicholas Crist was arrested for misdemeanor warrants, while Brandi Crist is being detained for a parole hold at the Dub Brassell Detention Center.
