An investigation into the shooting of 49ers star Keion White at a San Francisco nightclub earlier this year snowballed into a multi-state police probe, with four suspects arrested and a staggering stash of drugs and guns seized, authorities said.

The months-long investigation, dubbed “Operation D Line,” stretched from California to Georgia, bringing in more than 250 law enforcement personnel and yielding nearly 15 pounds of narcotics, according to the San Francisco Police Department.

The case stems from the Feb. 9 shooting of White, who was struck in the ankle while hosting a private party with rapper Lil Baby at the Dahlia Club in San Francisco’s Mission District following Super Bowl LX.

Dancers entertained guests on the club’s main floor while White’s party was downstairs in the VIP area.

The shooting left White with non-life threatening injuries, but the investigation that followed grew into a sprawling operation involving more than 50 search warrants.

In Southern California, Curtis Green, 35, was taken into custody at his Irvine home on Oct. 7, while Los Angeles police arrested Gregory Walker, 36, on Oct. 9. Both were booked into San Francisco County Jail three days later.

According to court documents, Walker and another man who has not yet been charged allegedly fired their guns during the nightclub incident, striking White. Green was also allegedly armed and brandished a firearm.

The investigation also led authorities to Atlanta, where cops arrested Marquis Davis, 38, at his home on Oct. 7, police said. Officers recovered an illegal firearm, 3,842 grams of fentanyl, 1,026 grams of methamphetamine, 979 grams of cocaine and 820 grams of MDMA.

That same day, Antoine Washington, 36, was arrested in Stockton, Calif., by San Francisco police and San Joaquin County sheriff’s deputies. A loaded firearm, more than 120 oxycodone pills and about $6,691 in cash were recovered.

White has recorded three sacks through the 49ers first five games of the 2026 season.

Authorities are working to bring Davis and Washington to San Francisco as the investigation continues.

Walker faces charges including assault with a semiautomatic firearm, with allegations that he personally fired a weapon and inflicted great bodily injury. Green faces misdemeanor charges involving brandishing a firearm and carrying concealed and loaded guns in public.

San Francisco District Attorney Brooke Jenkins plans to seek Walker’s detention without bail, arguing he poses a public safety risk. Walker and Green were scheduled to be arraigned Wednesday.

Police are also asking additional witnesses and victims connected to the February shooting to come forward.

White, meanwhile, has been making noise on the field.

The defensive end has recorded three sacks through the team’s first five games of the 2026 season.
