Syed Rizwan Farook, one of the shooters last Wednesday in San Bernardino that left 14 dead and 17 injured, received a wire transfer of $28,500 just two weeks before his fatal attack.

Citing a source “close to the investigation,” Fox News says Nov. 18 Farook had $28,500 placed in his bank account from WebBank.com. On Nov. 20 he took out $10,000 in cash, and in the days leading up to the attack he made a series of $5,000 transfers to his mother.

Fox says FBI investigators are still trying to determine whether the money was a loan or perhaps came from a different source.

Regardless of where the money came from, its presence is a very strong piece of evidence that the attack on Inland Regional Center was premeditated by Farook and his wife Tashfeen Malik, and was not the product of an argument at a holiday party. Fox’s source describes the money as “significant evidence of premeditation.”

The FBI is apparently investigating whether the $10,000 was used to reimburse Enrique Marquez, a friend who legally purchased the semiautomatic rifles used in the attack.

Farook’s personal finances are a subject of interest for law enforcement. Despite being a public employee with a salary of only $53,000 a year, he possessed a substantial arsenal of guns, ammunition, and bomb-making equipment worth thousands of dollars.

WebBank.com would not comment to Fox about the transaction.
