We now know the person who witnessed the explosive altercation between HGTV's Flip or Flop stars and told police he saw Tarek El Moussa run into the woods with a gun is Christina El Moussa's new boyfriend.

TMZ noted that Gary Anderson, a contractor, was working at a property near the El Moussa's house on the night cops were called to the home for a report of a "possibly suicidal male with a gun." Anderson is the man who told authorities that he saw Christina's husband run out of his home and into the woods.

Eleven deputies and one helicopter unit searched for Tarek on the hiking trail and when they caught up to him had him drop his weapon without incident. Five guns including an AR-15 rifle were then confiscated from the home.

As we reported, after that evening the El Moussas began living apart and started seeing other people and it was during that time that Christina and Anderson's friendship turned romantic.
