(KRON) — The San Francisco Police Department made an arrest Thursday morning in the stabbing death of Cash App founder Bob Lee. Records for the San Francisco County Jail confirmed the suspect arrested is Nima Momeni, a fellow tech executive who Lee reportedly knew.

The San Francisco Police Department confirmed Momeni, 38, of Emeryville, as the suspect in the killing. Jail records show Momeni was booked on a single count of murder Thursday morning. Inmate record shows Momeni is currently in custody with no bail.

According to a LinkedIn profile, Momeni is the owner of tech consulting firm Expand IT based in Emeryville and has been since 2010. Before that, Momeni worked in IT for several years at various companies. Momeni attended UC Berkeley, according to his LinkedIn profile.

Mission Local first reported Momeni’s arrest, reporting that the two were driving together through Downtown San Francisco before getting into an argument in the car leading up to Momeni stabbing Lee several times.

Officers confirmed that Momeni and Lee knew each other but did not go into details on how the two knew each other. Police said they have served multiple other search warrants but Momeni is their prime suspect.

“This is not about San Francisco, it happened in San Francisco…but this case is more about human nature,” SFPD Chief Bill Scott said at a news conference.

The investigation is ongoing.
