Police said a body found in a North Dakota river on Sunday is that of a 22-year-old woman who was eight months pregnant when she went missing earlier this month in Fargo, North Dakota, police confirmed in a press conference.
Savanna LaFontaine-Greywind‘s body was found wrapped in plastic in the Red River near Harwood, North Dakota, just before 6 p.m., Fargo Police Chief David Todd announced in a Sunday night news conference, according to CBS News.
Authorities said kayakers first spotted the remains and called police, CBS reports. Police were also investigating a nearby farmstead, which authorities said may be a crime scene.
Fargo police did not immediately respond to a request for comment from PEOPLE.
The gruesome discovery comes more than a week after LaFontaine-Greywind vanished from her apartment building in Fargo on Aug. 19. Days after she went missing, police found who they believed to be her newborn daughter — allegedly with her neighbors.
William Henry Hoehn, 32, and 38-year-old Brooke Lynn Crews were arrested on suspicion of conspiracy to commit kidnapping in connection with LaFontaine-Greywind’s disappearance.
Police said then that Crews’s and Hoehn’s apartment is in the same building where LaFontaine-Greywind lives with her parents and 16-year-old brother.
Both LaFontaine-Greywind’s cause of death and the manner in which she may have given birth remain unclear.
Hoehn and Crews allegedly gave police information that led them to believe the baby is LaFontaine-Greywind’s child but are not answering questions about the young woman’s whereabouts, police have said.

Hoehn and Crews remained in jail on Monday and it is unclear whether they have entered pleas or retained attorneys.
LaFontaine-Greywind was last seen that Saturday after a woman living in a third-floor apartment knocked on her family’s basement door, asking LaFontaine-Greywind if she would model a dress the woman was sewing, the Forum News Service reported.
The expectant mother agreed, left the apartment without her wallet and never returned.
“I immediately knew something was wrong because [my daughter’s] car is here,” her mother told the Forum News Service.
“She’s eight-months pregnant. Her feet were swollen so she wouldn’t have taken up walking like that. There was pizza here that she hadn’t eaten. She would not just leave that lady’s apartment and go somewhere.”
