The San Francisco field office of the Federal Bureau of Investigation is asking the public for help identifying a white van tied to the shooting of two Federal Protective Service officers at the Oakland Federal building. 

The FBI released photos of a white van, identified as a 1997-2002 Ford E-250 or E-350 Cargo Van, they believe was driven by people involved in the shooting. Investigators say the van appeared not to have license plates at the time of the shooting, around 9:45 p.m. May 29.

The agency is also seeking surveillance camera footage from businesses and private residences in the area of downtown Oakland surrounding the Ronald V. Dellums Federal Building and U.S. Courthouse from 7 p.m. to 11 p.m. from that night. "If you believe you may have videos or photos of the van, please preserve the footage and contact the FBI," the agency said. The FBI is also seeking information on 9mm firearms that may have been used.

According to officials, two Federal Protective Service contract security officers were shot in the incident, with one, Dave Patrick Underwood, 53, of Pinole, succumbing to his wounds. The shooting occurred on a night when a crowd of about 7,500 were protesting the death of George Floyd in the nearby downtown area. A spokesman for the Northern District's U.S. Attorney's office said that as of Thursday the other officer, who has not been identified, was "expected to recover." 

Department of Homeland Security Acting Deputy Secretary Ken Cuccinelli said in a Washington, D.C., press conference after the shooting that "when someone targets a police officer or a police station with an intention to do harm and intimidate—that is an act of domestic terrorism."

On Tuesday, Oakland Acting Police Chief Susan Manheimer said that Underwood's killing was targeted.

"We have reason to believe that these individuals were targeting uniformed officers and we know that they were out and about in the area of where our officers and others were stationed," Manheimer said.
