More than two full days after tech executive Bob Lee was fatally stabbed in downtown San Francisco, there still have no arrests or suspects named but the city's police chef expressed confidence that his officers would solve the case.

San Francisco police found Lee, 43, on the sidewalk in front of a condominium building with stab wounds shortly after 2:35 a.m. Tuesday. He was taken to a hospital, where he died. He leaves behind two children.

When asked by CBS News Bay Area if the attack was targeted or random, San Francisco Police Chief Bill Scott replied: "It's early to tell. What I will tell you is our homicide team is working tirelessly to get this to a resolution. We have a lot that's on our plate with this investigation and following up on things that need to be followed up on. We'll put the information out but we don't want to do anything to compromise this investigation."

Scott maintained that the department has a team of "very excellent homicide investigators" on the case and touted the department's clearance rate of 80%-85% on homicide cases year to date.

"I have 100% confidence in this unit," Scott said.

The neighborhood where the stabbing occurred is near the Embarcadero waterfront and full of tech offices, towering condominium buildings and not much else late at night.

According to the San Francisco Standard, Lee can be heard screaming "Help! Someone stabbed me!" in the audio of the 911 call he made with his cell phone prior to officers arriving. The San Francisco Standard also reported that Lee could be seen in surveillance video from a nearby building walking west up Main Street after being mortally injured. The video reportedly showed him walking up to a parked car that had its hazard lights on and lifting his shirt — apparently to show his wound as he asked for help — before the vehicle drove away.

The security camera video showed him walking toward the Portside condo complex and collapsing less than 20 feet from the front door after the car drove off. Officers arrived and located the stabbing victim, who was later identified as Lee. Officers began life-saving aid until medics arrived; Lee died of his injuries at the hospital.

Lee is known for creating the widely used mobile payment service Cash App while working as chief technology officer of the payment company Square, now known as Block. He was the chief product officer for the cryptocurrency firm MobileCoin at the time of his death.

Lee was back in San Francisco for a visit after moving to Miami in October, his father, Rick Lee, said on social media. The two had been living in the San Francisco suburb of Mill Valley.

"Bob would give you the shirt off his back," Rick Lee wrote. "He would never look down on anyone and adhered to a strict no-judgment philosophy. Bobby worked harder than anyone and was the smartest person I have ever known."

San Francisco Police Sgt. Adam Lobsinger said in a video message Thursday that the investigation is still early and the department would not comment on evidence or speculate on circumstances.

Lee defied the arrogant and self-centered "tech bro" stereotype affixed to certain men in the San Francisco Bay Area tech scene, and instead exuded an "innate kindness," said longtime friend Tommy Sowers.

Sowers and Lee first met at a fundraiser in Washington, D.C., where Sowers, a former Green Beret and Iraq war veteran, was running for Congress. Lee, newly hired at Square, was touting an app that could help his campaign fundraising. Both men were from Missouri.

Lee's two children joined the men on hikes and dinners. It was not unusual for Lee to be out late, said Sowers, and he loved San Francisco.

"I'd want to go to bed at like 9. He talked me into going someplace till midnight, and then he'd be like, 'Well, there's another one,' and you'd go to that. And he's like, 'There's another one.' He just had real boundless energy."

Part of those late-night sessions involved talking about technology, including San Francisco's unique role far away from the political power in Washington and the big money in New York.

"San Francisco is all about the idea, and you're as good as your current or next idea," said Sowers, who, with Lee's counsel, went on to start his own real estate technology company and now works for a North Carolina-based private jet company.

Sowers said he doesn't know the origins of the "Crazy Bob" handle Lee used on Twitter.

"But it fit. Not in a way of being reckless, but, he was kind of up for anything."

Lee was also generous with his time coaching and championing fellow engineers and entrepreneurs, said Wesley Chan, co-founder of FPV Ventures. The two met more than a decade ago when they both worked at Google, where Lee helped to build the Android smartphone operating system before its 2008 release.

Lee's death has further enflamed debate over public safety in San Francisco and its moribund downtown, which has not yet bounced back from the pandemic. Twitter's owner Elon Musk took to the social media site to post that "violent crime in SF is horrific and even if attackers are caught, they are often released immediately." Musk tagged the city's district attorney in the post.

San Francisco suffers from property crime more than violent crime such as murder, rape, robbery and assault. In a statement, San Francisco Mayor London Breed called the homicide "a horrible tragedy" and said that the city is prioritizing public safety.

Sowers said it's hard to picture what led to Lee's violent death.

"I can't imagine a situation where he would instigate a conflict," he said. "That's the tragedy of it."

Meanwhile, San Francisco Fire Commissioner Don Carmignani was seriously injured in a brutal attack Thursday outside his mother's home in the Marina District, CBS Bay Area reported

According to friends, Carmignani was he leaving the family home on Magnolia Street between Buchanan and Laguna streets on Wednesday when he was approached by three men.

The three men beat Carmignani with a pipe, leaving him with severe head injuries including a fractured skull. He was rushed to San Francisco General and underwent emergency surgery. His condition has not been released.

At a community meeting Thursday night on neighborhood safety in the city's Sunset District, Police Chief Scott said an arrest has been made, but did not disclose any other details.

"Our hearts go out to he and his family," Scott told CBS Bay Area. "He's expected to survive his injuries which is good news. But these types of brutal attacks and these types of brazen attacks. These are the kinds of things that have people anxious."
