A 5-month-old baby girl died Tuesday night after being left in a minivan car seat in Moorhead, Minn. while her father was taking care of five other children under the age of 7.
Officers responded to the report of an unresponsive child at 8:22 p.m. in a residential area. Police Lt. Chris Carey said she had been left in the minivan for an "extended period of time," possibly four hours, the Fargo Forum reports.
She was moved to a nearby apartment where first responders tried CPR, but she was pronounced dead at the scene.
Police identified the baby's parents as Andrew Sandstrom, 24, and Shayna Sandstrom, 27.
Andrew Sandstrom dropped his wife off at work Tuesday afternoon and returned home to the couple's apartment with six children and forgot about the infant while unloading the others. Police said the family's apartment has "extreme filth and was unsafe for the other children."
Police Lt. Tory Jacobson said Clay County Social Services will investigate to ensure the children are living in a safe environment, and will help the children cope with their loss.
"During the initial investigation, it appeared accidental," Carey said.
Moorhead's weather forecast registered a high temperature of 82 on Tuesday. Jacobson said the windows of the van appeared to have been closed.
Carey said the investigation is ongoing.
