SAN FRANCISCO—A suspect was arrested on Friday, July 29 after a year-long investigation connected to a quadruple homicide, according to a press release from the San Francisco Police Department.

Four victims were found shot in their vehicle on January 9, 2015 in the Hayes Valley neighborhood at Laguna and Dage Streets by officers responding to a shooting call. Manuel O’Neal, David Saucier II, Harith Atchan and Yalani Chinyamurindi suffered multiple gunshot wounds. The responding officers called for an ambulance and rendered aid, but all four victims died from injuries they sustained.

The SFPD Homicide Investigation conducted the investigation with assistance from the Northern Police Stations Street Crimes and Housing Units, Gang Task Force, Fugitive Extradition Unit, Forensic Services Firearms Unit, Crime Scene Investigation Unit, Special Investigations Division, and other local and Federal partner agencies. After more than a year of following leads and gathering evidence, authorities were able to develop probable cause to arrest Lee Farley, 27, from San Francisco in connection to the crime.

On July 29, at approximately 9:00 a.m., Farley was taken into custody without incident in Atwater, California at the U.S. Prison on an unrelated charge. He was later booked at the San Francisco County Jail on four counts of murder, four counts of shooting at an inhabited vehicle, one count of possession of a firearm by a convicted narcotics offender, and one count of participation in a criminal street gang.

“I was the Officer in Charge of the Homicide Detail at the time of this homicide and later promoted to Commander of Investigations.  I promised the victims’ families that the San Francisco Police Department would do everything we could to solve this brutal crime,” said Acting Chief of Police Toney Chaplin.  “I have been updated regularly by the Homicide Detail and I am happy to announce that the Department has arrested a suspect and begun the process of bringing justice and healing to the victims’ families.”

Even though a suspect has been arrested the investigation is still ongoing. Anyone with information regarding the case can contact the Homicide Detail at (415) 553-1145, the Anonymous Tip Line at (415) 575-4444, or Text A Tip to TIP411 with “SFPD” at the beginning of the message.
