Four men have been arrested in connection with the shooting of San Francisco 49ers defensive lineman Keion White at a nightclub in February, including a man who was taken into custody in Stockton and another who lives in Mountain House, authorities said.
San Francisco police officers and deputies with the San Joaquin County Sheriff’s Office took Antoine Washington, 36, into custody Oct. 7 in Stockton. During his arrest, officers said they recovered a loaded firearm, more than 120 oxycodone pills and $6,691 in cash.
Records from the San Joaquin County Jail show Washington remains in custody on a dozen felony charges.
Two days after Washington’s arrest, the Los Angeles Police Department arrested Gregory Walker, a 36-year-old Mountain House resident. Walker was booked into the San Francisco County Jail on Monday on charges of assault with a semi-automatic firearm, which prosecutors with the San Francisco District Attorney’s Office say he fired.
District Attorney Brooke Jenkins said prosecutors say Walker poses a public safety risk and would seek no bail for him.
The arrests stem from a Feb. 9 incident at a private event at the Dahlia Lounge SF nightclub in the 1700 block of Mission Street in San Francisco. Authorities say White, a defensive end for 49ers , was hosting a private party following Super Bowl LX, which was held at Levi’s Stadium in Santa Clara — the 49ers home field.
San Francisco Police Chief Derrick Lew said just after 4 a.m., multiple armed suspects “confronted” White, who was shot in the ankle during the altercation. Reports from the team at the time indicated that White, 27, who has played for the 49ers since 2025, underwent successful surgery.
Investigators used video footage and witness accounts from the party to identify the suspect, Lew said.
A monthslong investigation dubbed “Operation D-Line” followed. The case has involved more than 50 search warrants and assistance from over 250 law enforcement personnel nationwide, resulting in arrest warrants for Washington, Walker and two other men — Curtis Green and Marquis Davis — authorities said.
Green, 35, was arrested Oct. 7 at his Irvine home on a warrant related to the shooting allegations. Like Walker, he was taken to San Francisco and booked into the jail on Monday on charges including assault with a firearm. He faces misdemeanor charges of brandishing a firearm and carrying a concealed and loaded gun in public, Jenkins said.
Davis, 38, was also arrested Oct. 7. Atlanta police took him into custody at his Georgia residence, where officials say they found an illegal firearm; 820 grams of MDMA , a synthetic drug commonly known by the street names ecstasy or molly; 1,026 grams of methamphetamine; 979 grams of cocaine; and 3,842 grams of fentanyl.
The San Francisco DA’s Office is working with San Joaquin County and Atlanta authorities to arrange for Washington and Davis to be brought to San Francisco to face charges.
