- Authorities are investigating what they called the "murder" of Cash App founder Bob Lee.
- The SFPD chief said Thursday there are "good developments" in the investigation, per ABC's KGO-TV.
San Francisco's law enforcement officials said they are still investigating the death of Cash App founder Bob Lee, amid news reports of surveillance videos that appeared to show him seeking help after the attack.
San Francisco police chief Bill Scott declined to provide details of the investigation during a town hall on Thursday, saying, "there's evidence that we found that I can't talk about because we don't want to jeopardize this case," according to a report by ABC's San Francisco affiliate, KGO-TV.
"There are some good developments on this case — I apologize, but that's as much as I can say at this point," he said, calling Lee's death a "murder," per the local news segment on the community meeting.
Scott had previously said that Lee called 911 after his attack on Tuesday morning, according to the outlet, which also cited unnamed sources to report that a "silver kitchen knife with a four inch blade" was found near the site of Lee's attack in the city's downtown Rincon Hill neighborhood, though it's not clear if it's been linked to his death.
Representatives for the San Francisco police department and the city's department of emergency management did not respond to Insider's requests for comment on Friday.
Lee, who was chief product officer at fintech company MobileCoin, was seen attempting to get help on Main Street close to the Oakland Bay Bridge, according to an earlier report by KGO-TV, which cited sources describing camera videos.
The San Francisco police previously said in a statement that they responded to a call regarding the attack early morning on Tuesday at 2:35 a.m.
The city's District Attorney Brooke Jenkins and Mayor London Breed have both released messages of condolence to Lee's family.
"Unfortunately this is one that's going to take time to solve," Jenkins told KGO-TV on Thursday, according to the outlet.
The District Attorney's office can't make a determination on bringing charges until police have concluded their investigation and made an arrest, a representative for the DA's office previously told Insider.
