(CNN) -- Bob Lee, the former chief technology officer of Square who helped launch Cash App, has died after an apparent stabbing attack in San Francisco.
Lee's death was confirmed by Josh Goldbard, the CEO of his current employer, MobileCoin. Lee joined MobileCoin, a cryptocurrency and digital payments startup, in 2021 as its chief product officer.
"Our dear friend and colleague, Bob Lee passed away yesterday at the age of 43, survived by a loving family and collection of close friends and collaborators," Goldbard said in a statement to CNN Wednesday morning. "Bob was a dynamo, a force of nature. Bob was the genuine article. He was made for the world that is being born right now, he was a child of dreams, and whatever he imagined, no matter how crazy, he made real."
Goldbard continued: "We will miss you Bob. We love you."
According to a statement from the San Francisco Police Department, officers responded to the report of a stabbing early Tuesday morning in the Rincon area of San Francisco, where they found "a 43-year-old adult male victim suffering from apparent stab wounds."
"Officers rendered aid and summoned medics to the scene. The victim was transported to a local hospital with life-threatening injuries. Despite efforts by first responders and medical personnel, the victim succumbed to his injuries," the police statement said.
Multiple local news organizations cited unnamed police sources saying Lee was the victim of the stabbing. Police indicated no arrests have been made and that the investigation remains active.
San Francisco has been grappling with an apparent uptick in crime as it still attempts to bounce back from the pandemic.
While Goldbard did not provide the circumstances of Lee's death in his statement, he wrote in a separate Twitter thread reacting to the news that, "As a lifelong Bay Area resident I have more questions than answers tonight."
"I don't know how to fix what's wrong, but I know something isn't working in our grey city. Bob left this world too soon," Goldbard wrote on Twitter.
