A missing baby has been found dead near a North Dakota slough after a five-day search, authorities said Saturday.

According to KSFY, Carrington police began searching for the 4-month-old baby and his mother, Justice Lange of Fargo, on Monday after family members requested a welfare check and reported a stolen vehicle. On Friday, a farmer reportedly found Lange near Woodworth and took her to her grandmother's house. Police said Lange told her grandmother that she had no memory of the past four days, the Pioneer Press reported.
