LOS ANGELES (CNN) — Enrique Marquez, friend of San Bernardino gunman Syed Farook, has been arrested, CNN reported Thursday.
According to CNN, the charges against Marquez are expected to partly be based on allegations that he had purchased two rifles that Farook and Farook’s wife used in the December 2 mass shooting and terror attack that left 14 people dead in San Bernardino.
Details about when the charges would be filed weren’t immediately available.
Marquez, 24, previously told investigators he didn’t know about the plans for the San Bernardino attack, U.S. officials have said.
But he has acknowledged that he bought the two AR-15s for Farook several years ago, and he told investigators about a 2012 attack plot that he said he and Farook conceived but did not carry out, U.S. officials told CNN.
Since the San Bernardino shootings, he has waived his Miranda rights, cooperated with investigators and provided information, according to the officials. Marquez also checked himself into a mental health facility, CNN reported.
Farook and his wife, Tashfeen Malik, opened fire on Farook’s coworkers during a workplace holiday party. The couple were shot and killed by police hours later.
Authorities have deemed the shooting a terror attack.
Both U.S.-born Farook and Pakistan native Malik expressed commitment to Islamic jihad and martyrdom in direct, private online messages in late 2013, months before Malik moved to the United States to live with Farook, FBI Director James Comey has said.
Malik also pledged allegiance to ISIS leader Abu Bakr al-Badghadi in a Facebook post as the San Bernardino attack was happening, three U.S. officials familiar with the investigation told CNN.
Authorities still are trying to learn more about whom the killers interacted with, how they hatched and carried out the plot and why.
