A Missouri mom was accused of leaving her 1-year-old baby alone for hours at a time and neglected to feed the child for 43 hours, reportedly because she “had a migraine.”

According to the Missouri Highway Patrol’s Division of Drug and Crime Control, Alyssa Wehmeyer, 21, was investigated following the “suspicious” death of her 1-year-old on Feb. 28. In a press release, police said that the baby had shown signs of “severe malnutrition and neglect, resulting in the child’s death.” Further details in the probable cause affidavit revealed that Wehmeyer allegedly last fed her baby on Feb. 26. The affidavit stated that the baby was found deceased on Feb. 28 and an autopsy was conducted. The cause of death was determined to be dehydration, and there was reportedly “very little evidence of food in the stomach.” Wehmeyer was taken into custody by police and read her rights, after which she was interviewed.
