A two-day-old baby was found in the North Dakota apartment building where a missing pregnant woman was last seen before she vanished.

Savanna Lafontaine-Greywind, 22, went missing Saturday after she went to visit a neighbor in her North Fargo apartment building for a dress fitting.

Her family, who says she is eight months pregnant, reported her disappearance that evening when she stopped answering their texts and calls, according to news station KVLY.

Fargo Police said that the newborn was found at the apartment complex Thursday afternoon and two people have been detained for questioning.

“We discovered an infant that appears to be a newborn infant. At this point in time, we’re not able to confirm if that newborn infant is Savannah Greywind’s child or not,” Fargo Police Chief David Todd said in a Facebook video.

It is not clear where in the apartment complex the baby was found, but the infant was healthy and brought to a hospital.

Todd said Lafontaine-Greywind was not in the apartment and there was no new information about her whereabouts. Police are treating the case as a criminal investigation.

“This is at a critical juncture of the investigation and we want to make sure we are as thorough as possible so we can get correct answers to all the questions people have,” Todd said.
