San Francisco Police Arrest Wanted Shooting Suspect and Investigate Catalytic Converter Thieves Who Fired at Officers 23-011

In two separate and unrelated recent incidents, suspects discharged their firearms while San Francisco Police officers were attempting to take them into custody. This information is being released publicly to highlight positive outcomes from these incidents and support the excellent work performed by SFPD officers. In these incidents, SFPD officers encountered very dangerous and life-threatening circumstances that could have had a different outcome if not for the restraint, composure, and professionalism displayed by all involved officers.

In an internal message to SFPD officers regarding the incidents, Chief Scott said:

“In the past two weeks, there have been two disturbing and unacceptable incidents of armed suspects resisting arrest with shots fired at or in the immediate vicinity of SFPD officers. In both incidents, the involved officers exhibited valor, courage, and a reverence for the sanctity of human life in the way they responded to these life-threatening situations.”

“The work that the officers of the SFPD do day in and day out to resolve life-threatening situations and take dangerous people off of our streets oftentimes goes unheralded and does not get the credit or attention it deserves when outcomes are positive, and the incidents don’t result in the use of lethal force.”

On January 23, 2023, SFPD officers assigned to Crime Gun Investigations Center (CGIC) were in the area of 100 Brookdale, investigating a suspect who was involved in multiple shooting incidents. After CGIC officers located the suspect and identified themselves, the suspect fled and pulled out a firearm. Officers reported that as the suspect swung his arm towards them, one SFPD officer began to grab the suspect, and a shot was fired. The suspect was simultaneously tackled and disarmed. SFPD officers took the suspect into custody and discovered he had multiple firearms and magazines in his possession. The suspect was identified as 24-year-old Spencer Hansen-Mukomela.

This case has been presented to the San Francisco District Attorney’s Office. On Wednesday, January 25, 2023, District Attorney Brooke Jenkins filed seventeen (17) felony charges against Hasen-Mukomela associated with four shooting-related incidents. Charges stemming from the January 23, 2023 incident against SFPD officers include assault on a peace officer with a firearm (245(d)(2) PC) with allegations of personal use of a firearm (12022.5(a) PC) and personal and intentional discharge of a firearm (12022.53(c) PC); resisting an executive officer in performance of duty (69(a) PC); taking a vehicle without consent (10851 CVC), and felony firearm possession charges related to the illegal possession of three firearms, including two ghost guns.

In addition to the unacceptable violent resistance against SFPD CGIC officers, there was a similar incident on January 17, 2023, just six days prior when Richmond Station officers responded to a call of a catalytic converter theft in progress. Responding officers located a vehicle with multiple suspects in the area of McAllister and Arguello. SFPD officers reported that during the foot pursuit, one of the suspects fired multiple rounds at them. One suspect has been arrested. The SFPD Burglary Unit is leading the investigation and SFPD officers are working tirelessly to locate and capture the remaining suspects, including the suspect that fired at officers.

These remain open and active investigations. Anyone with information is asked to call the SFPD Tip Line at 1-415-575-4444 or Text a Tip to TIP411 and begin the text message with SFPD. You may remain anonymous.
