Police this morning arrested a suspect in the January 2015 Hayes Valley quadruple homicide that many feared would go unsolved. In a press release sent out this afternoon, city officials say police took the suspect into custody this morning at 9:00 a.m.

The shooting went down at Laguna and Page Streets on Friday, January 9 of last year. Four men sitting in a car were shot to death in a murder that SFPD believed was tied to a Western Addition gang. Yalani Chinyamurindi, 19, of San Francisco; Harith Atchan, 21, of San Francisco; David Saucier, 20, of Antioch; and 22-year-old Manuel O’Neal all died at the scene.

“I was the Officer in Charge of the Homicide Detail at the time of this homicide and later promoted to Commander of Investigations," Acting Chief of Police Toney Chaplin said in a statement today. "I promised the victims’ families that the San Francisco Police Department would do everything we could to solve this brutal crime. 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.”

Police were able to arrest the suspect, 27-year-old San Francisco resident Lee Farley, without incident likely because he was already in jail — the U.S. Prison at Atwater, California, to be specific.

Farley has been charged with "four counts of murder (187 PC-Felony), four counts of shooting at an inhabited vehicle (246 PC-Felony), one count of possession of a firearm by a convicted narcotics offender, (29800 (a) (1) PC-Felony) and one count of participation in a criminal street gang (186.22 (a) PC-Felony)." A booking photo has not been released as of this time.
