Amber Scholz, 36, instigated an altercation and her husband, Charles Fowler-Scholz, 34, was involved in a fight before the shooting at the Sports Corner Cafe in the Old Sacramento area on Monday night, police said. The couple were arrested Friday on suspicion of assault with a deadly weapon.
Police did not release details, and did not immediately return a call from The Associated Press.
The suspected gunman in the shooting - Carlito Montoya - is also in custody. The 22-year-old was wounded by an armed security guard at the bar. He ran out of the bar toward a street crowded with holiday revelers but was caught quickly by officers chasing him, police said.
Montoya was in custody at an undisclosed hospital where he was being treated for his wounds.
The security guard and a 30-year-old woman at the bar were also wounded. Police said their injuries were not considered to be life threatening.
The shooting prompted police to cancel Sacramento's New Year's Eve midnight fireworks show that was expected to draw as many as 40,000 people. The pyrotechnics were instead detonated on Tuesday morning, startling residents of neighborhoods along the Sacramento River, according to the Sacramento Bee.
