The radicalized San Bernardino gunman clashed with a Jewish co-worker over religion just two weeks before he and his Pakistani wife stormed an office holiday party where they massacred 14 people.
Syed Farook, 28, got into a heated argument with colleague Nicholas Thalasinos, a Messianic Jew who was identified today as one of the victims of Wednesday’s rampage.
It came as FBI agents discovered a huge arsenal of weapons and pipe bombs at a California home linked to Farook and his wife Tashfeen Malik.
Agents discovered nearly 5,000 rounds of ammunition, a dozen pipe bombs and hundreds of tools for making improvised explosive devices at the property, law enforcement officials revealed today.
It also emerged that the US-born Farook appeared to have been radicalized and was in touch by phone and via social media with more than one international terrorism subject, which may have in part motivated the attacks, CNN reported, citing investigators.
And it is unclear if the earlier argument between Farook and Thalasinos played any role in the massacre – but authorities said Farook had left the party ‘angry’.
