HARRISBURG, Pa. (WHTM) — A Harrisburg man convicted of helping ISIS will spend 13 years behind bars.

Jalil Ibn Ameer Aziz, 20, pleaded guilty earlier this year to conspiracy to provide material support and resources to a designated foreign terrorist organization and transmitting a communication containing a threat to injure.

U.S. District Court Chief Judge Christopher C. Conner sentenced Aziz to 13 years in prison, with 12 years probation. The judge sentenced Aziz below the minimum, saying Aziz promoted violent acts but did not commit any.

Aziz is accused of using Twitter to spread ISIS propaganda, actively recruit new members, and share the names and addresses of about 100 American service members with statements such as “kill them in their own lands” and “behead them in their own homes.”

His defense attorney said his client was an outcast, loner, and a ”wanna-be.” He says Aziz posted the tweets supporting ISIS to feel a part of something. The defense attorney and Aziz’s siblings also said he was neglected by his parents for years.

Authorities also suspect Aziz may have been plotting an attack before his arrest in December 2015. They said a backpack in his closet had five high-capacity magazines loaded with ammunition, a modified kitchen knife, a thumb drive, medication, and a balaclava.
