San Bernardino shooting planned a year in advance:

Last week's mass shooting in San Bernardino, Calif., that killed 14 was reportedly planned up to a year in advance.

The suspected killers began practicing with guns and making financial preparations in 2014, according to NBC News.

Syed Farook and Tashfeen Malik began honing their firearms skills last year at a shooting range in Riverside, Calif., NBC said, citing two sources.

Couterterrorism officials said the pair began making monetary savings for their child and Farook’s mother during the same period.

“[They wanted to] take care of both Grandma and the baby,” one official told NBC News, referencing the couple’s six-month old daughter and Rafia Farook, 62.

“They had purposely thought through that problem,” they continued. "[Some transactions] would be consistent with them making preparations for grandma and the kid.”

“There were other indications of preparation,” the official added, not specifying further details.
