For a month, the country has wondered what happened to 20-year-old Mollie Tibbetts. The young woman went for a run one day and never returned. Her family waited, praying she would return  safely. Those prayers were dashed yesterday when a body believed to be Mollie’s was discovered in a field near of Brooklyn, Iowa. Charged with her murder is 24-year-old Cristhian Bahena Rivera. It is bad enough to know a promising young college student will never again return home, her life cut short in an act of violence. Worse, Rivera is an illegal alien — sorry, undocumented immigrant — who has lived in the area for some years. The real slap in the face, however, is the lack of outrage by the media. Buried in the vast majority of the coverage about Mollie’s murder is the fact she was killed by someone in this country illegally.
