A multi-state police probe triggered by the February nightclub shooting of 49ers defensive end Keion White has ended with four arrests and a major narcotics and weapons haul, authorities announced.
The monthslong inquiry, dubbed “Operation D Line,” roped in more than 250 law enforcement personnel and spanned from California to Georgia, the San Francisco Police Department said. Investigators executed more than 50 search warrants before the case wrapped.
White, who has recorded three sacks through San Francisco’s first five games of the 2026 season, was struck in the ankle during the Feb. 9 incident at the Dahlia Club in the city’s Mission District. The injury was non-life threatening.
The shooting erupted while White was hosting a private afterparty with rapper Lil Baby following Super Bowl LX. Dancers performed on the club’s main floor as White’s gathering occupied the downstairs VIP area.
In Southern California, Curtis Green, 35, was arrested at his Irvine home on Oct. 7, according to police. Los Angeles police picked up Gregory Walker, 36, two days later in their city. Both men were booked into San Francisco County Jail on Oct. 10.
Court documents indicate Walker and another man who has not yet been charged allegedly fired weapons during the nightclub incident, striking White. Green was allegedly armed and brandished a firearm, authorities said.
Walker faces charges including assault with a semiautomatic firearm, with allegations that he personally discharged a weapon and inflicted great bodily injury. Green faces misdemeanor counts of brandishing a firearm and carrying concealed and loaded guns in public.
San Francisco District Attorney Brooke Jenkins intends to seek Walker’s detention without bail, contending he presents a public safety risk. Walker and Green were scheduled to be arraigned Wednesday.
The investigation’s reach extended to Atlanta, where officers arrested Marquis Davis, 38, at his residence on Oct. 7. Police recovered an illegal firearm, 3,842 grams of fentanyl, 1,026 grams of methamphetamine, 979 grams of cocaine and 820 grams of MDMA from that location.
That same day, Antoine Washington, 36, was taken into custody in Stockton, Calif., by a joint team of San Francisco police and San Joaquin County sheriff’s deputies. A loaded firearm, more than 120 oxycodone pills and approximately $6,691 in cash were seized.
Authorities are working to extradite Davis and Washington to San Francisco as the probe continues.
Police have appealed for additional witnesses and victims connected to the February shooting to come forward.
White has remained productive on the field since the incident, building on a 2025 season where he established himself as a key piece of the 49ers’ defensive front.
The total narcotics seized across the operation approached nearly 15 pounds, according to the department’s tally.
