A 20-year-old North Carolina man accused of murdering his neighbor and offering to pay someone to kill his own parents pleaded guilty on Tuesday to plotting mass shooting attacks in the name of Islamic State.
Justin Sullivan admitted to one count of attempting to commit an act of terrorism transcending national boundaries in federal court in Asheville, North Carolina.
The plea agreement calls for a sentence of life in prison.
US prosecutors said Sullivan conspired with Junaid Hussain, a British hacker who was an active online recruiter of people to carry out attacks on behalf of the militant group Islamic State. Hussain was killed by a US military air strike in Syria last year.
