Jaelyn Young, Mississippi College Student Who Tried to Join ISIS, Is Sentenced to Prison

A former Mississippi college student was just sentenced to 12 years in prison by a federal judge on Thursday for trying to join ISIS, according to the Associated Press.

Jaelyn Young, a former chemistry major at Mississippi State University who was once an honors student and cheerleader, was caught trying to travel to Syria to join the Islamic State with her fiancé, Muhammad Dakhlalla, last year. Prosecutors said that Jaelyn — who converted to Islam while studying at MSU and began expressing views that the United States didn’t treat Muslims well — was the one who came up with the idea and began urging her boyfriend to join ISIS with her.

The pair had allegedly contacted undercover agents online to find out how to travel to Syria to join the group, and then were arrested at an airport in Mississippi with tickets to Istanbul, Turkey, The Daily Mail reported.

“I found the contacts, made arrangements, planned the departure,” Jaelyn wrote in a letter that she had left behind for her family, according to the AP. “I am guilty of what you soon will find out.”

During sentencing on Thursday, the 20-year-old broke down crying and said she was ashamed of what she’d done. Jaelyn pleaded guilty in March to providing material support to a terrorist organization, and faced up to 20 years in prison.

Muhammad also pleaded guilty and will be sentenced on Aug. 24. Prosecutors said that she urged her fiancé to go along with the plan.

“Young continually asked Dakhlalla when they were going to join (the Islamic State group) and began to express hatred for the U.S. government and to express support for the implementation of Sharia law in the United States,” prosecutors wrote.
