RICHLAND COUNTY, SC (WIS) -
Richland County Sheriff's deputies have arrested a detention officer they say shot a pregnant woman and set her body on fire last week.
A spokesperson for the Richland County Sheriff's Department said 23-year-old Tristan Gist has been charged with murder and death or injury of a child in utero due to commission of a violent crime.
Gist was taken into custody without incident at his home Monday afternoon. He's been identified as a detention officer at Alvin S. Glenn Detention Center.
Authorities identified the victim as 22-year-old Dierra Fisher.
Fisher's body was found in a five acre woods fire near the 3200 block of Screaming Eagle Road Thursday afternoon. She was 21 weeks pregnant.
Investigators say Gist shot Fisher and then drover her body to the wooded location. Inside the car with Fisher's body were two young children, investigators said.
Once they arrived to Screaming Eagle road, Gist removed Fisher from the vehicle and set her body on fire.
Richland County Coroner Gary Watts tentatively released the name of the victim, Dierra Fisher, pending positive identification from medical records. Watts says Fisher died as a result of a single gunshot wound to the head.
According to deputies, the two have a child together.
Richland County Sheriff Leon Lott said this was "a horrible act of domestic violence."
Gist was booked and transported to the Lexington County Detention Center. According to a South Carolina criminal background check, Gist has no prior arrests in the state.
