A 20-year-old Mississippi woman pleaded guilty Tuesday to charges she sought to join ISIS by going to Syria on her honeymoon. Jaelyn Young accepted a plea bargain on the charges and could face as much as 20 years in prison. Her 23-year-old fiancé, Muhammad Dakhlalla, pleaded guilty to similar charges this month. The pair were arrested last year when attempting to board a flight to Istanbul and making contact with undercover FBI agents. She reportedly converted to Islam while studying at Mississippi State University.
