Glenda Ross, mother of the 7-year-old girl who lost her arm in a Scott City railroad accident, will be in court today for the first time. Ross, 34, was arrested by the St. Louis Police Department and returned Saturday to Scott County by the Scott City Police Department, Sheriff Rick Walter said Monday. Ross was being held Monday in the Scott County jail on a $75,000 bond. She goes before Associate Circuit Judge David Mann for arraignment today. Ross faces three charges of first-degree child endangerment. Mikala Morrow lost her arm Oct. 30 when a train started moving as she, a sister and a friend were crossing under it between cars with Ross and Ross's boyfriend. The southbound train was parked and began moving after allowing a northbound train to pass. The boyfriend has not been charged.
