Valencia went into the backyard, but another of Lamadrid’s sons began arguing with the older man, blaming him for the confrontation, the warrants said. Lamadrid told him to leave, and he complied.
Once the other son left, Valencia returned to the house and continued arguing with Lamadrid, the news station reported. Lamadrid took his son's luggage and tossed it onto the back porch.
The son Valencia had been arguing with threw the bags into the yard, at which point Valencia started throwing patio furniture, according to the warrants. He also threw a water bottle at his father, who was still holding the shotgun.
Lamadrid told investigators the bottle struck him in the face, causing him to squeeze the trigger, CBS 17 reported. Valencia was struck in the hand and the leg.
After checking on his son, Lamadrid said he went inside to dress and await police, the warrants said.
The highly divisive NFL protests began in 2016 when then-San Francisco 49ers quarterback Colin Kaepernick began taking a knee during the pre-game national anthem to protest racial injustice and police brutality against black suspects.
Kaepernick’s protest set off nationwide protests and condemnation from opponents who believe the protests disrespect the flag and the military.
