A $28,500 deposit was made to Syed Farook’s bank account from WebBank.com on or about Nov.18, some two weeks before he and his wife Tashfeen Malik carried out the San Bernardino massacre, a source close to the investigation told Fox News Monday.

Investigators are exploring whether the transaction was a loan taken out by Farook, who with his wife killed 14 and wounded 21 when they opened fire at a holiday lunch. He earned $53,000 a year with the county as an environmental health inspector. Investigators are also exploring the possibility that a subsequent cash withdrawal was used to reimburse Enrique Marquez, the man who bought the two AR-15 semiautomatic rifles used in the San Bernardino shootings. Marquez, who could be charged, especially if it is determined that he illegally modified the weapons, is now reportedly answering investigators’ questions.

“Right now our major concern at the FBI, the ATF, and the JTTF (Joint Terrorism Task Force) is determining how those firearms, the rifles in particular, got from Marquez to Farook and to Malik,” assistant special agent in charge with the Bureau of Alcohol, Tobacco and Firearms, John D’Angelo, told reporters in California Monday.
