A 21-year-old man on Monday was shot and killed in Vallejo during an officer-involved shooting after a fight broke out outside of a house party, police said.
Officers responded to a residence located along the 1700 block of Sacramento Street just before 12:45 a.m. to find two people entangled in a physical brawl, police said. A 16-year-old boy had been knocked to the ground, and the knife-wielding 21-year-old man was spotted by police to be standing over the teenager.
One of the responding officers determined that the 21-year-old man presented "an immediate and lethal threat to the victim." The officer proceeded to open fire.
The knife-wielding man "was struck multiple times" before being pronounced dead at the scene, police said.
The deceased man's brother, who did not want to be identified, offered a different account of the shooting.
"It wasn't like (my brother) just got into a fight with the guy and tried killing him," the brother said. "That's not what happened. (My brother) was protecting me and police seen it as he was trying to kill him."
Police were originally alerted to the scene after receiving calls about loud noises and arguing. The deceased man's brother said it was simply a family gathering with some drinking involved.
The deceased man's identification has yet to be released, according to police. Police said the 16-year-old boy was from Union City.
Authorities in Solano County are investigating the shooting.
