A 33-year-old Eagan home daycare provider has been charged with assault for inflicting serious injuries on a 13-month-old boy in her care. Officials say on September 22nd Mariel Grimm reported an unresponsive child. A child abuse pediatrician later examined the boy and found no medical cause to account for the severe brain injury he sustained. The expert ruled the injury could *not* have been caused by a short fall, or injury from another young child in the daycare and that the injury was similar to the type of trauma associated with “a violent acceleration-deceleration event, such as a vehicle collision or if a child is violently shaken or thrown.” Grimm’s first court appearance has not yet been set.
