Watch a Timeline of the San Bernardino Shooting

On Wednesday, two suspects opened fire on a gathering at the Inland Regional Center in San Bernardino, Ca., killing 14 people and injured over a dozen more. The suspected shooters are Syed Rizwan Farook and Tashfeen Malik, who were husband and wife. The two had reportedly been married for two years, and both were killed in a shootout with police. Farook and Malik are believed to have stockpiled ammunition and supplies to make bombs. Federal investigators are currently looking for a motive for the shooting, which President Obama said terrorism is a possibility, but “we don’t know.”
