These are the faces of homegrown terrorists. Remember, many of these were also immigrants - just like the ones that Obama wants bring to America by the thousands. (Via CBS News) CBS - The young people joining violent terrorist organizations -- like ISIS and al-Shabab -- hail from all different walks of life and are very rarely what you'd expect. In August 2015, for example, two recently married Mississippi State students were arrested trying to join ISIS. Officials say that Muhammad Oda Dakhlalla, 22, and Jaelyn Delshaun Young, 20, conspired to get married, so that they could travel to Turkey and ultimately Syria, under the guise of the trip being their honeymoon.

Muthana graduated from Hoover High School in 2013, going on to study business at the University of Alabama. Her classmates describe her as quiet and reserved; not at all the sort of person you would expect to join a violent terrorist organization.

Hussnain Javid, who attended Red Bank High School with Abdulazeez, said he was popular and a member of the school's wrestling team.

He and his older brother, Tamerlan, assembled and then strategically placed bombs near the finish line, killing three people and wounding nearly 200. At the time of the bombing, Dzhokhar was a college student at UMass Dartmouth, majoring in Marine Biology. He was also an all-star wrestler, and the captain of his high school's team. Dzhokhar was later sentenced to death for his crimes.

An aspiring heavyweight boxer, Tamerlan dropped out of community college -- where he was studying to become an engineer -- to focus on the sport. He was the New England Golden Gloves heavyweight champion from 2009-10; telling a Boston University graduate student publication that same year that he was working to become a naturalized citizen before the next Olympics, so that he could compete on the U.S. Boxing Team. Tamerlan died after a car chase and shoot out with police.

When authorities arrested him on July 4, 2015, they found rifles, handguns, machetes and several partially constructed molotov cocktails in his possession. A recent convert to Islam, Alexander Ciccolo is now accused of plotting aterrorist attack on the dorms and cafeteria at a crowded state college campus.

He also allegedly wanted to use pressure cookers like the ones used in the Boston Marathon Bombings, an event at which his father was one of the first responders. During the course of the investigation, Ciccolo was recorded calling the June 2015 terrorist attack on a beach in Tunisia, "awesome." And authorities say that, like so many other young ISIS-inspired extremists, Ciccolo used social media to praise the terror group's work. He appeared in a U.S. District Court, July 14, 2015, and was held without bail because authorities consider him extremely dangerous. They say he acknowledged trying to build explosives with an accelerant that would stick to the skin, making the fire more difficult to put out. After his arrest, he reportedly stabbed a nurse with a pen, during a routine medical exam. CREDIT: Northern Berkshire District Court via AP See more: CBS News
