LOS ANGELES (Reuters) - A California man accused of buying assault-style rifles used by a married couple to massacre 14 people at a government office in San Bernardino in 2015 has agreed to plead guilty to conspiring to provide material support to terrorists, prosecutors said on Tuesday.
Enrique Marquez Jr., 25, will plead guilty to conspiring with Syed Rizwan Farook in 2011 and 2012 to attack a community college and commuters on a Southern California freeway, prosecutors said.
Marquez, a friend and former neighbor of Farook, has also agreed to plead guilty to making false statements about his purchase of two assault rifles used in the 2015 shooting rampage at the San Bernardino Inland Regional Center.
Marquez was scheduled to enter his pleas, part of an agreement with federal prosecutors, at a hearing on Thursday in U.S. District Court in Los Angeles. He faces a maximum sentence of 25 years in prison.
"This defendant collaborated with and purchased weapons for a man who carried out the devastating December 2, 2015 terrorist attack that took the lives of 14 innocent people, wounded nearly two dozen, and impacted our entire nation,” U.S. Attorney Eileen Decker said in a written statement announcing the plea deal.
Farook, 28, and his wife, Tashfeen Malik, 29, opened fire at a holiday gathering of Farook's co-workers on Dec. 2, 2015, killing 14 people and wounding 22.
Farook, the U.S.-born son of Pakistani immigrants, and Malik, a Pakistani native he married in Saudi Arabia in 2014, died in a shootout with police four hours after the massacre.
Authorities have said the couple were inspired by Islamist extremism. It was one of the deadliest attacks by militants in the United States since the Sept. 11, 2001, hijacked plane attacks.
Prosecutors say Marquez and Farook, who were childhood friends, plotted attacks together in 2011 and 2012 that were never carried out and it was during that time that Marquez purchased the two rifles that Farook and Malik ultimately used in San Bernardino.
Marquez did not take part in the San Bernardino massacre but was arrested about two weeks later and has remained in custody ever since.
He also faces immigration fraud charges in connection with his marriage to Russian-born Mariyah Chernykh, which prosecutors say was a sham.
Chernykh, 26, and Farook's brother, Syed Raheel Farook, 31, pleaded guilty in January to immigration fraud charges stemming from the marriage.
