Preliminary autopsy results have been released in the case of Savanna LaFontaine-Greywind.
On Tuesday, the Fargo Police Department announced on Facebook that the 22-year-old’s death was due to "homicidal violence."
“We are unable to release the specific details of Savanna’s death, or the manner in which Savanna’s baby was born,” they wrote on their Facebook.
LaFontaine-Greywind went missing August 19 when she was eight months pregnant. Her body was later found by kayakers in the Red River -- which borders North Dakota and Minnesota -- "heavily wrapped in plastic and duct tape" and stuck to a log.
Three days earlier, police found a baby in the North Dakota apartment of LaFontaine-Greywind’s neighbors, 32-year-old William Henry Hoehn and a 38-year-old Brooke Lynn Crews. Police believe the newborn girl belonged to LaFontaine-Greywind.
LaFontaine-Greywind was a member of the Spirit Lake Dakota tribe. According to the Star Tribune, her tragic case drew hundreds of tribal members from all over the Midwest to offer their help to LaFountaine-Greywind’s family.
“It’s hard for me to believe that she went through such a brutal ordeal,” Tarita Silk, the slain girl’s aunt told the Star Tribune. “We need to have some closure. We want to know what happened.”
Silk called LaFontaine-Greywind a gentle spirit who was excited about the impending birth of her baby girl, Haisley Jo.
According to the court documents obtained by PEOPLE, Hoehn told police he found Crews cleaning up blood in the bathroom upon coming home August 19. Crews was also holding a newborn girl. She allegedly told him, “This is our baby, this is our family.”
According to the Star Tribune, the suspects have a violent history. Court records reveal that Hoehn was convicted for pushing Crews into a bathtub during an argument. He was also convicted of felony child abuse, after he was responsible for injuring his infant son, who suffered multiple skull fractures while in his care.
Both suspects have been charged with conspiracy to commit murder, conspiracy to commit kidnapping and providing false information to law enforcement. They are being held without bond.
