Authorities say a 3-year-old Nebraska boy has died after a power car window closed on his neck, reports the AP. Colfax County Attorney Denise Kracl said Monday that 3-year-old Everton Isay Romero Romero was pronounced dead Friday at an Omaha hospital. Everton never regained consciousness after the rear window closed on him April 15 outside a store in Schuyler, where he lived. Kracl says no autopsy was performed because there's no evidence any law was violated. She says the boy's mother "acted appropriately the entire time." It was unclear how or when the window closed.
