The Justice Department has charged at least 60 individuals this year with terrorism-related crimes, an unprecedented number that officials attribute to a heightened threat from the Islamic State and the influence of social media on potential recruits.
Last week alone, prosecutors charged three people and convicted two others on terrorism-linked charges. One of those charged was Enrique Marquez Jr., a friend and neighbor of Syed Rizwan Farook, the male gunman who was killed in a firefight with police in the aftermath of the San Bernardino, Calif., shooting rampage this month. That terrorist attack killed 14 people.
A second was Mohamed Elshinawy, a Maryland man accused of receiving at least $8,700 from the Islamic State overseas and planning to use the money to carry out attacks in the United States. He told prosecutors that a childhood friend had connected him through social media with an Islamic State operative.
