An American national has been sentenced to 20 years in jail for buying guns for a married couple who carried out a mass shooting in California in 2015.
Enrique Marquez Jr, 28, was found guilty of supplying the weapons to Syed Rizwan Farook and Tashfeen Malik.
The pair fired on a group of people in San Bernardino whom Farook worked with, as they gathered for a Christmas party.
After killing 14 people and wounding 22 others, Farook and Malik died during a shootout with authorities.
Marquez, who authorities said had been exposed to radical Islam by Farook, bought the weapons in 2011 and 2012 and said on a purchase application form that they were for his own use.
Prosecutors argued that Marquez had a high IQ and the mental capacity to understand what the guns would be used for.
Marquez pleaded guilty in 2017 to providing material support to terrorists and making false statements regarding the rifles, which he bought with money from Farook.
