In a press conference with San Francisco Mayor London Breed, San Francisco Police Chief William Scott and District Attorney Brooke Jenkins, the SFPD announced an arrest in the killing of Cash App founder Bob Lee.
Nima Momeni was named as a suspect by San Francisco Police Chief William Scott on Thursday, April 13. He confirmed that Momeni was arrested in the killing of Lee.
Scott said that the investigation is still open and ongoing, but confirmed that Momeni and Lee knew each other, though he declined to give more detail.
Jenkins announced charges of murder against Momeni. She expects the arraignment to occur on April 14.
Lee was stabbed in early April on the streets of San Francisco. According to a release from the San Francisco police department, the assault took place in the early morning — around 2 am.
“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 release said.
Scott’s comments echo previous reporting from media reports, which stated that the suspect knew Lee. San Francisco Supervisor Aaron Peskin told NBC Bay Area that the killing “was not a random act,” though he did not offer further details.
Prior to his death, Lee was the chief product officer at MobileCoin, a cryptocurrency company. He helped found Cash App in 2013.
Following the news, the MobileCoin account tweeted that Lee was a “force of nature” and “made for the world that is being born right now.”
“Bob was a force of nature. Helped to birth Android and Cash App into our world. Moby was his dream: a privacy protecting wallet for the 21st Century. I will miss him every day,” Joshua Goldbard, MobileCoin’s CEO, previously told Blockworks.
